To use it as a bag-space creator, simply send excess items to the bank alt whenever you're near a mailbox for a low price of only 30 a slot. Even if you accidentally send the wrong item to the bank alt, it can be returned-to-sender for free. It's very quick, due to the fact that sending mail between characters on the same account is always instant.
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).
War Mode: War Mode can be turned on at level 30 through your talent window, and will give you 10% bonus XP. You will, however, be attackable by players of the opposing faction, but changes have been made so that all players have a fair shot in a fight and even low-level players can kill much higher level players, and at least not get ganked and one shotted. Note: As of patch 8.1, you can get an additional call to arms bonus with war mode on if your faction is underepresented.
While not as powerful as it was before 7.3, this transmog spot is a good area to amass a large number of BOE greens that generally fly around the 35 – 42 area.  It's popularity stemming from the amount of items that drop (and the potential value of those items) rather than the quality of each drop itself. Generally drops from these farms can take a while to sell even when using my TSM posting style.  However if your low on transmog stock this can be an awesome area to hit every now and then.
The raid is made up of eight bosses that each have interesting and unique mechanics. Some bosses might put extra pressure on the DPS players to kill an add before it can heal the boss, while others might require players to move around the environment in a specific pattern or order, all the while still doing as much damage to the boss as possible or keeping the group alive through healing. While past raids often repeated mechanics or had one or two boring fights that didn’t ask much of the players, each encounter in Uldir feels unique and challenging. It’s been a long time since we had a raid where each fight was as much fun to do over and over again as the fights in Uldir.

The other addons are a great addition to the repertoire of the gold maker. Some add percentages and buying lists, while others provide price and revenue graphs to the reader. Chatter even allows you to repeat those WTS messages without sifting through pointless gossip and chatter. The in-depth workings of them will come later, as for now, more basic setup needs to be covered first.

An important aspect to crafting professions in BfA are the warfront contributions. During the contribution phase of a war front you will have to turn in various crafted items to help the war effort. During this time you can make gold with all the professions in the game if you are crafting the items that are currently required for turn-ins. This effect is pretty much the same across all the professions, so I will not be mentioning it specifically.

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.
For more than a year in WOTLK I did nothing but raiding and some dailies here and there. I leveled a bit on a few alts and, as all are aware, it cost to support alts sometimes. I did dailies, and LFG quests until the Dungeon finder came along. I did 2 or 3 randoms then logged off if not a raid night. I was bored with the grind of dailies and wanted a change.
If you are just coming out of Level 110, you will probably have a number of different Legendary items to choose from. Your Legendaries' special effects will stop working at Level 116, but until then they can be a very powerful addition to help you level up quickly. These are our Legendary recommendations for leveling as a Arcane Mage in Battle for Azeroth:
Each pet has 3 abilities it can use during a battle, but a total of 6 to choose from. They will also have a total of 3 active spell slots that show which abilities can be used during a Pet Battle. The first spell slot will already be unlocked, but the second and third will only become available once the companion has reached a certain level. Other spells will also unlock after reaching higher levels.
Recipes - provide in-game capability to create more kinds of items, and so are always in demand, BUT be careful; if the ingredients are obscure, and the benefits marginal, or the recipe is too common, this is not a good option. Some otherwise very good recipes drop far to often to hold value - Copper Chain Vest comes to mind. This produces an excellent entry-level item, but the recipe is available for low silver at the auction house.
This is cumulative, as you take into account each failed sale as a loss. In the event too many deposits accumulate, you must decide whether to continue selling the item inflated by too many sales or finding of another way to dispose of it. One final tip: when you find that an item fails to sell in one AH, selling it on the other may finally dispose of it and get you your earnings.
You can earn a decent amount of XP by doing Herbalism or mining. Any zone works but I prefer Sholazar Basin as a lot of the mobs are not aggressive and the mobs are spread out so you will find a lot of herbs and ore that you don’t have to fight for. It is possible to make about a level every hour by doing this, or a level every 30-40 minutes with rest XP.
-Island Expeditions- Island expeditions was one of the new features I was looking forward to but Blizzard no longer makes games that are ready when they are ready but rather makes games ready when the deadline comes. Thus, many of the new features are completely stripped down from what was expected and it's literally just a small scenario you enter with two other players to continue to grind out your Azerite neck piece.

Well, I think, a “wall of of text” is not defined by the amount of characters. To create a wall of text you need two things: lots of characters, and lots of missing line breaks / paragraphs. I’m completely aware of that, and I’m always trying to section and format my texts in a manner that makes it usable for readers ;) I think the limit of 990 chars is not contributing to avoid walls of text. (It’s easy to build a a wall of text with only 500 chars, but I think you got what I mean…)
When it comes to gold making addons, as most of you know, there is one that comes before all the rest, Tradeskill Master. This addon will help you make heaps of gold on the auctions house, and will give you a deeper understanding of your servers economy and the whole WoW economy. Learning how to use it well takes time, so read through all the info on their site and maybe watch some youtube videos on how to set up TSM. TSM will help you appraise items, sell items quickly on the AH and buy items that you can resell for a profit, amongst other things. Additionally the addon will help vendor and managing your mailbox, making this the only addon you need for gold making purposes. We will be coming back to TSM in the Auction house part of the guide.
