WOW Power Leveling: Good equipment is a blue-named two-star item with decent stats
Sell the good items: To players, that is. If you got WOW Power Leveling nice equipment drop from a monster, your best option would be to sell it to a player, because they're usually worth a lot more than the NPC will pay you.
Good equipment is usually a blue-named two-star item with decent stats (By which I mean a magic weapon with accuracy does NOT have decent stats). Now, there are three types of people:
People who sell their items through chat, this is usually not a great option. Trade chat in West Archo can get you a buyer sometimes, but it's usually not very effective.
People who sell their items through a 'cat shop', this is a good option for the medium-priced items.
People who sell their items through the auction, this is a great option for the medium to high-priced items. You can set a minimum bid (and a buyout price), then just go grind.
After 24 hours, the item will get sold to the highest bidder (earlier if someone payed the buyout price). Downside is that you have to pay to use the auction. Costs are negligible though; just make sure you'll get more money out of it than you put in.
