I like hack and slash!!! And im not alone.
Besides see nothing wrong with item prices... If u dont have the money to buy the best itens u have to ways of solving the prob: buy stuff u can afford even if its not the very best, or play more time to get stuff u can sell or trade!!

Mmorpg or hack and slash people are going to farm anyways just because one thing: they want to..
None of those cazy or not so crazy ideas are going to stop people from farming. That's called free will.
