Tailoring is a crafting profession that turns various forms of cloth into cloth gear. You can also create some tailoring only mounts. In BfA tailoring has several markets that are good from a gold making point of view. You can utilize the Tidespray linen bracers in the scrapper to get access to cheap expulsom. You can also craft the item level 300/310 tailoring armor. This armor does require expulsom, so it takes a bit more work than the blacksmithing gear. You can also craft bags, which typically is quite in demand as players always want more bag slots.
The same goes for the level 40 mount. An elite ground mount means still-faster leveling. Not only that, but you'll get knocked off considerably less often by mobs while getting around inside zones, meaning you'll die less often as well. Remember, as the goblins are so fond of saying, "Time is money, friend!" So it behooves you to get an elite ground mount as rapidly as possible.
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 Horde will now control most of Kalimdor, and the Alliance most of the Eastern Kingdoms. For a low-level character the quests and storylines won't change, but for high-level players many zones will see changes via phasing. Teldrassil is burned and Undercity is in ruins as the story progresses by phasing. At max level Arathi Highlands and Darkshore are phased to be updated to reflect their status as locations for Warfronts.
I now have a Patreon Page where you guys can support me while I work on Vanilla WoW leveling guides every day. I appreciate all of you who support me on there, it means a lot to me right now. Doing this full time is taxing on my financial situation. My goal is to make the best Vanilla WoW leveling guides on the web and the donations keep me going at it healthfully. There is also cool rewards you get in return for donating. Thanks!
Whatever your approach, if you use some common sense and apply yourself, you can make significant quantities of money in the game. By managing your cashflow, conserving and budgeting where you can, and investing wisely in those activities that make you money, you can become financially solvent relatively early in your career, and remain comfortably well-off (while still buying good gear) at level 80. Good luck!
I dont know if this exist already, if it does I couldnt find one, but it would be nice to have a guide with the location of all daily quest broken down by Alliance, Horde, Faction, Neutral, etc. I know there can be variable quest for things like Fishing and Cooking but just having the location for those quest givers would be great. If it were a stand alone addon that would be even better!
