| As i posted in another thread also, i'd advise you to go with Mining and Jewelcrafting for a while. Do that til you manage to gather 2-3-4k gold, to have some to start. Also try to farm some level 10-60 instances for green and blues and try to stack them on alts.
At the ponit where you are confident with your gold drop Mining and start leveling Enchanting. All the items gathered will help you get some mats that might be more expensive on AH to level enchanting. When you managed to level to 325 enchanting, the way to get rich is :
1. Buy Saronite ore of AH (20-25 gold / stack) or try to find a constant provider at start (to buy 5-10 stacks / day, more in time)
2. Prospect all the saronite you get
3. Cut the blue gems and sell them on AH
4. Craft green items with JC out of green gems and Crystalised earth (cheap on AH or from a saronite ore provider)
5. D/E the green items for dust or better mats
6. Sell the mats on AH
As a sided advice i'd say that gems and enchanting mats should sell best Wednesday/Thursday and Saturday/Sunday. The reason is simple, most guilds clear all the content on the first days after reset (that is wednesday and thursday) and some casual tend to play more during the weekend , when they have time to PuG (saturday and sunday). When people clear instances they get gear that needs gems and enchants !
Hopefuly this will help and manage to sort your gold problem.  |
