The most important part of saving is to never buy equipment unless you're positive that it will increase your earning potential, or significantly speed your character's leveling progress. While it is true that gear is important (particularly for melee combat characters), it is also true that an overemphasis on having great gear before maximum level is dumb. Who cares if you're wearing a green sword at level 43? If you're advancing well, you aren't going to be level 43 for very long anyway. The only gear that currently "counts" is max level gear.

This includes the “Tides of Vengeance” campaign missions, which continue the War campaign introduced when the expansion launched. Two new island expeditions called Jorundall and Havenswood were also added. Weekly quests also require less Azerite than they did in the past, Mythic and player-versus-player islands award more Artifact power, and new vendors were made available.

Dugi’s leveling guide is the leveling addon I’ve always used to level as fast as possible. It will show you where to go and what to do in-game, speeding up the leveling process. This is optional though, as the game already does a pretty good job at showing you where to go at all times. The addon does, however, come with a couple of other nice features and perks.
In 2019, World of Warcraft is attempting the careful balancing act of maintaining a social space for players, single-player campaign content, dungeons and raids, and daily activities and progression. All of these activities tie into advancing the player’s character, growing stronger and unlocking new abilities. Patch 8.2, aka Rise of Azshara, is the largest content patch in World of Warcraft yet, and it’s meant to shore up the weaknesses of Battle for Azeroth.
Just before Battle for Azeroth goes live, you will want to log all of your characters out in the zone of Silithus so that you can acquire the quest to talk to Magni and obtain your Heart of Azeroth (refer to our Heart of Azeroth guide for more information about this item). This is the new artifact-type of piece of equipment that you will use for all of the Battle for Azeroth expansion. Once you acquire your permanent neck slot piece of equipment, get back to Stormwind or Orgrimmar to begin your scenario that leads into the introductory areas of Kul Tiras and Zandalar.
Azeroth paid a terrible price to end the apocalyptic march of the Legion’s crusade—but even as the world’s wounds are tended, it is the shattered trust between the Alliance and Horde that may prove hardest to mend. As this age-old conflict reignites, gather your allies and champion your faction’s cause—for Azeroth’s future will be forged in the fires of war.
Rogues can make fast money from pickpocketing mobs, opening lockboxes and selling items that drop from those on the AH. If you don't have a rogue make one and get him to at least level 16. Rogues can also make some money by picking locks for people and getting tips. Not a great revenue source, but a decent one to supplement multiple strategies for making money. Generally, the usual lockpicking tip is between 50s to 1 gold, the most common being 50 silver. Sometimes, you can get lucky and have someone tip up to 5 gold for lockpicking several (or even just one) boxes. It's always beneficial for a rogue spending time doing repairing, training, etc. in a city to put up a lockpicking advertisement on the trade channel. Just make sure you let the buyers decide the price and that your lockpicking level is high enough.

World of Warcraft offers a lot of ways to make money (gold). There is no one "right" way to make money, although there are some definite wrong ways! Some people like to play the Auction House, some people do their daily quests, some people tend to farm, etc. Many characters do a combination of all three of these along with other activities. Below is a compendium of money-making methods.

Much like an encounter with a wild pet team, PVP Pet Battles are turn-based. However, unlike the PVE version, the PVP combat system is timed and any ability for each round must be chosen within that time limit otherwise it will assume you have passed a turn. A time penalty is applied if you take more than 15 seconds to choose an action, resulting in progressively shorter round timers for you.
Level 120 comes and goes. Island Expeditions have unlocked, but it turns out they’re not much fun, and the most rewarding versions are only accessible to premade groups. You turn to Warfronts only to realize they’re not available this week. Fine. You can always grind out better gear. Except as you do, you notice your new gear has higher Azerite requirements than your old gear, which means your shiny new items have fewer unlocked traits than what they replaced. Discouraged, you decide to roll as one of the cool new Allied Races. Except you can’t because they’re all locked behind reputation grinds.
The story up until 8.2 has been focused nearly entirely on red versus blue — the battle between the Horde and Alliance. “There’s been a lot of strong opinions,” says Hazzikostas, “because there are a lot of strong connections to these characters, especially on the Horde side.” Saurfang and Sylvanas, the Battle of Dazar’Alor, and Jaina’s narrative arc are all stories that the team consider successful.
Similar problems have risen in the leveling system, which automatically scales to the player’s level and equipment. For the most part, you’ll vaporize enemies more quickly as you gain power, but there are some weird dips. Many players complained they felt less powerful at level 119 than at level 110, a problem I experienced myself. And world PvP remains a strange and whacky world where level and class balance issues make wins and losses feel destined instead of earned.
Step-by-step class guides are on the way!  The 1-12 Mulgore Guide is the first guide to get all the individual class steps.  At the top of the guide, simply select which class you are playing and the page will dynamically update all the steps in the guide for that class (both text and images).  The rest of the guides will be slowly updated overtime to include all the class steps, but you can see how it's going to work with the 1-12 Mulgore.  I want to thank crazyK and his Placeholderguild for helping me out with the individual class content.  They are allowing me to get the 1-60 Alliance guide done while also getting all the class steps done at the same time, so everything can be ready for Classic launch (hopefully).
Anything that can be answered by reading the recent discussions on the subreddit, has a yes/no response or can be looked up on sites in the community resources should not be posted in a thread of its own. Questions such as 'What is this worth?', 'Did I make a mistake?', 'What do I do with XYZ?' or 'Should I buy/sell this?' will be directed to the Daily Questions sticky.
As a hero of the mighty Alliance, journey to the seafaring kingdom of Kul Tiras, home of Jaina Proudmoore. Untangle a web of betrayal and dark magic as you encounter power-hungry pirates, witches wielding death magic, mystical sea priests, and more. Explore the stony peaks of Tiragarde Sound, trek across Drustvar’s high plains and red forests, and navigate the intricate inland canals of Stormsong Valley as you convince this fractured kingdom to join your cause.

The quality of captured wild pets is random. As of patch 5.1, upon entering a battle the Pet Battle UI shows the quality of a wild pet (idicated by a color-coded border around its icon). If you're farming a specific quality, if you forfeit the match your team will incur a small damage penalty (roughly 10%). There is no accurate way to determine a pet's quality prior to the start of a battle.

At the end of Legion, the titan Sargeras was imprisoned, but not before he plunged his sword into the planet Azeroth. This not only devastated a massive area (much of the desert zone of Silithus is now cracked and scorched), but badly wounded the gestating titan inside. While the heroes managed to ablate the worst of the damage (at the cost of the majority of their artifact weapons' mythic power), the world is still wounded and bleeding a substance called "Azerite," which has great magical potential. The Horde Warchief, Sylvanas Windrunner, attempts to consolidate Horde power on Kalimdor and gain a monopoly on Azerite (which is primarily found at the southern end of the continent). Her campaign to do so, the War of Thorns, formed a pre-launch event for the expansion and ends with the major Night Elf holdings on the continent seized or (in the case of their capital city of Darnassus) annihilated. The Alliance makes a retaliatory strike against her home base, the Undercity, which was formerly the human capital of Lordaeron. This succeeds in driving the Horde out, but before leaving Sylvanas saturates the area with disease and toxins that render it uninhabitable. With this tit-for-tat military exchange, the Horde has almost complete control over Kalimdor, while the Alliance has near-total dominion over the Eastern Kingdoms.[4] With further conflict inevitable, Battle for Azeroth takes the two factions to the continents of Kul Tiras and Zandalar to recruit new allies in order to turn the tides of war.[4]

This is a once size fits all pet farm that can generally leave you with a small sum of gold if your server is low on this specific pet. (You can always check on the undermine journal).  It takes place in the Ihgaluk crag and is generally performed by sweeping the oozes in the small muddy pools surrounding the area.  An easy spot to hit, that really isn't farmed all to often.  I was able to get one in the video after a small 24 minutes.

Anyway, however you choose to get to the addon's menu, choose guide list and then pick the zone you want to quest in. There are some zones that will autoselect based on quests in your log, but not all guides or all quests are set up that way. (If you don't want to switch to a guide that auto-pops up choose "not now" or "never") As you can see in the screenshot, there are various categories of guides. Most max level content (such as Argus) is found in Achievements rather than leveling.
Tiragarde Sound and Stormsong Valley are both fairly similar zones, but Stormsong is a little longer, meaning that you might not even have to finish it to hit 120. Tiragarde also comes with a bit of a warning. There are plenty of side quests to do in the zone after you finish the story quests. Don’t do them. It’s not worth the time or the experience you’ll get.
Certain locations in World of Warcraft – primarily inns, capital cities, and private instanced zones like your garrison or class order hall – are rest areas. You know you’ve entered one because your character portrait will gain a “Zzz” icon where your level is normally shown, and because you can immediately log out of the game instead of waiting 20 seconds.
Materials ('mats') - items that get used in professions. This is driven more by use than by source; for example, copper is very easy to mine, but it is widely in demand, and you can often find bargains in copper, bargains you can profit from. Contrarily, some very scarce mats may have low demand, may only be used in one mediocre recipe, and may not sell.
That being said, there are occasions when a little kindness is not unwarranted. A typical example is a new player who just dinged level 20. They are suddenly confronted with a whole set of relatively expensive skills at his or her class trainer, and the cost of mount and riding training, and needs a small amount of money to learn those new skills. Likewise, sometimes one sees a player who, just by the way he or she walks, is clearly a new player. Kindness to non-whiny, well-intentioned, legitimately inquisitive newbies is karmically rewarding, and one should not worry about shelling out an occasional boon to such players. Remember, at that level, a few gold can go a long way. Heck, even a few older bags that you have lying around collecting dust in your vault will often be much appreciated.
One thing to realize is that once you hit 15 you have a lot more options for speedy leveling. Right now (you seem to be level 9 at the time of this writing) you only have questing and grinding, which are inefficient. Once you get the ability to use the Random Dungeon Finder (often called LFD, Looking for Dungeon) you can queue for dungeons in between questing. Often one dungeon, up until 25 or so, will give you most of a whole level off the XP and quests within.
