Use Lil Sparky's Workshop, Auctioneer and Ackis Recipee List (see the setup post in this "whatprof" series) to work out what will sell.
- Potentially higher gold/hour than farming
- Nice clothes
- Different approaches to gold making - basic and advanced
- High cost items can be difficult to sell. These professions have some of the highest cost items.
- Gear Obsolescence even at maximum level.
- Competition often works for tips (which is better than being in competition with bots)
The levelling toon has difficulties making money, but it is still possible. Make a mix of items and slowly feed them into the market.
There are types of items that can sell well, however they will be pointed out by Lil Sparky
- Quest Items(e.g. Hillman's cloak)
- Starter gear like level 20 hats, lv 40 chain/plate, or tanking gear because a player is looking to fill a specific slot.
- Items in a levelling guide. Everyone else is makeing them and not enough toons buying. These generally have the 'fewest mats'
- Chest and shoulders sell poorly because many many levelling toons have BOA gear for the XP bonus.
- leg enchants (tailors and leatherworkers)
- belt buckles (blacksmiths)
- various bags (primarily tailors)
- Improved cloth - making bolts, imbued bolts, extra special bolts (mooncloth, spellweave etc). Many players seeking cut price tailors (eg guildies) will buy the immediate previous step and will pay for the cloth.
- Cloth cooldowns - the best cloths will have a cooldown to make. This makes for scarcity, and will guarantee an income (at least untill the cooldown gets removed)
- Improved leather (think heavy borean leather)
- Armor kits (leatherworkers) (depending on your server)
- Enchanters rods (blacksmiths)
- Sheild spikes and weapon chains (blacksmiths)
- PVP gear. Even at the end of Wrath, basic PVP gear still sold at a profit. I have read that "last season's" PVP gear will be craftable.
- Starter tank gear (mostly blacksmiths) as historically starter tanks need more gear than any other class
- The latest pattern - Every raid seems to create new patterns to learn and make that many part time crafters won't make.
