Blacksmithing is a crafting profession that uses bars obtained from melting ore to craft plate armor and weapons, as well as some assorted cosmetic items. In BfA you can currently craft armor and weapons that is item level 300 and can proc to 310. This gear does not require expulsom which is awesome as it makes it very easy to stock the items. The sale rate is really high and these items are surprisingly very good money makers.
A new quest will pop up once your first pet reaches level 3. It will send you to either Audrey Burnhep in Stormwind or Varzok in Orgrimmar. These trainers will offer a quest chain to battle specific Pet Tamer NPCs on each continent. Defeating each of these NPCs will reward a nice chunk of experience for your pets, as well a Sack of Pet Supplies (which has the chance to drop the Porcupette companion, among the always-useful pet bandages).
The old popular example was the This item differed on my server from a high of 6k to a low of about 3k. When the price was down at 3k, I would buy a few of these and just wait a week. Throughout the week, I would put in trade and the auction house that I wanted 6k for it. I would then immediately go onto an alt and say that I only wanted 5200g. Sometimes, I would get the 5200g and be a very happy man, other times it would take more patience. However, almost always, by the end of the week, the other sellers had reposted for around what I wanted. This gave me a huge advantage. Now, the price ceiling was no longer 3k on the auction house, but 5k. I could now easily sell the few I bought for 4 or 4.5k, which is a huge 50% profit from the 3k I originally invested.
As for Battle for Azeroth’s lack of new 120 talents, Hazzikostas explains it as a tough scenario. If the designers come up with three new abilities for rogue or death knights, those classes may not necessarily need three new abilities. Those abilities may be filler, or they may shore up a weakness in the class design and remove counterplay. That being said, Hazzikostas does agree that “it’s possible we’ve gone too far.” 

A common mistake of new players is to upgrade their gear at every opportunity, paying for a new piece even if it will only add one or two new stat points over an existing item. Likewise, investing in headgear, neckwear, trinkets, and rings at the earliest available levels can also consume valuable cash. While it might seem foolish to leave an available slot empty, you will eventually find something to fill it. Blizzard will see to it via the quest rewards you'll get along the way. In the mean time, the 1 or more you save will serve you well if you invest it wisely. The bottom line is that one can easily level all the way to the maximum relying on just quest/drop greens. The gear you get from regular questing can help you perform well in dungeons, which gets you even better equipment.
For those interested in more details on spending wisely, and generating good cashflow, we cover a number of topics in more detail. Please note that this guide represents the accumulated wisdom of many people. You don't necessarily have to do all of these things--there is no one "right" way to make and manage money. However, these pointers will give you ideas on how to establish a firm financial foundation for your character.
Thanks for this guide. In the preparation section, you could add Goblin Gliders which are always super useful. I also recommend picking Northrend Engineering and Draenor Archeology as temporary professions. The first allows the use of the loot-a-rang toy which allows looting movs from a distance. The second one is required to picknsome treasures in Draenor.
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.
Thanks for reporting. Yes, it looks like a false positive. However, this is a generic rule that has been in the database for over a year. So I'm thinking something with Zygor guide's was updated and therefore it is now detected by us. We'll see what we can do on our end to avoid further wrongful detection. In the meantime, I recommend adding these detections to your exclusions list. Here's how:
Elemental items (Primals, Eternals, etc.) can be a good source of money, because they are always in demand on the AH. See which mobs you will most benefit from farming, then set out for a few hours. In the process you will also most likely collect significant vendor trash, and may get other profitable item drops as well. Note, however, that older elemental drops usually lose profitability compared to newer ones, i.e. Primal Water sold well to level 70 players in BC, but sells far less well to level 80 players in WotLK, because level 80 gear requires Eternal this'n'that.

These are Warlock- and Mage-only skills which can net you some money. It's not much, but a few gold is worth it. Note that Mages have an easier time with this than Warlocks as Warlocks need to be at the location for the summoning and need an additional person (a 3rd) for the group to help out with the summons. Mages only need the reagent to open the portal. While the Warlock doesn't incur a cost (except the loss of a soul shard), the Mage will typically be more successful at finding employment using this method.
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.
