I usually try to combine leveling with gold farming because old mats are usually worth a lot of gold and thatās something i wouldāve farmed anyway. I can thus level a character and still feel like i did some progress rather than wasting my time (and if your AH is merciful and you do it properly you may even get enough to buy a month of sub with gold by leveling an alt)
Hereās the breakdown : Donāt forget to always pick mining and either herbalism or skinning. Youāll be able to change at max level donāt worry
1-60 : Whatever is close by until lvl 40 and then Winterspring/Blasted lands/Sillithus for one reason : Them Arcane crystals. Basically 1k gold for each crystal farmed, pretty good overall and one of the few vanilla resource worth farming. Oh yeah and warbear leather if i picked skinningā¦
==========================================================================
60-80 : Time to waste ? Go BC and focus blade edge (if skinning) and Nagrand (mining). Expensive and hard to sell stuff, but still a nice additional income if you have the most elusive recipes. Any elemental resource is worth a lot of gold, especially air motes. So kill, kill, kill and kill some more elementals as you pass by, usually worth your time.
Want to get out of this hellish leveling range ? Worry not, Wotlk is there for you ! Howling fjord is one of the best zones to get your hands on some cobalt ore while leveling and itās hands down one of the most expensive basic ore in the game, so thatās pretty good. Then target some of the highest level zones for Titanium ore or go to Stormpeaks if youāre a skinner for jorgunnar scales (misspelled the name, but smh expensive mat). Sholazar basin was pretty good for instance.
==========================================================================
Cata vs Mop : mop has some cool zones, but worthless mats so iāll usually pick cata
Cata : Obsidium and herbs are your main focus here. Go to hyjal and complete the questline to unlock the molten front, especially if youāre a hunter. Youāll thank me later. Skinning is usually a bad choice here as the crafts are very expensive and not that interesting thus no real point in crafting anything imo.
Herbs and ore on the other hand are some of the most expensive all expansions combined, so youāll get a sizeable pile of gold by the time you finish this xpack.(multiple mounts and other goodies worth farming for) If youāre not done by the time you finish Hyjal, then consider deepholm (lots of herbs & obsidium) or twilight highlands (mostly elementium & pyrium)
==========================================================================
WoD : Youāre wasting your time here, do whatever you want thereās no gold to be made in this xpack with farming professions beside skinning but even that isnāt fundamentally worth your time.
==========================================================================
Legion : Leystone ore and herbs ! Lots of gold to be made here, and professions are a nice way to boost your leveling speed as each rank up quest gives you 20 or 30k xp. Pick any zone, do what you must and focus on the legion invasions as they give about 2.5 levels each
==========================================================================
BFA : At this point pick whichever profession you want to use at max level. Iād still suggest keeping a gathering profession but you do you. Also always keep any soulbound gear you got you hands on (or even BOE you dropped from mobs) if you intend to use any profession other than gathering or alchemy.
Youāll be able to get expulsom from the scrapper, and this is the most important resource for professions and gold making in BFA. (1 expulsom every 6 items scrapped. You also get 2 to 4 of the mats which were used to craft the item, especially important for LW as the mats required to craft any item is lower than BS or tailoring)
==========================================================================
Shadowlands ? We donāt even have a release date yet but at this point it seems that professions will be much more important and linked together which is imo a good thing. Iād suggest you start the xpack with at least one gathering profession.
