Wanna get gear? need gold.
How to get gold?
1. Flip items in AH.
4. Exploit commoditiy markets.
What about farming you may ask? nothing. It's like playing the national lottery with only 1 ticket vs people that have high paying jobs. How many people that play the lottery will win it? 1 in (insert random crazy high number).
So, whats left for normal, honest farmers? nothing. You can enjoy the combat in the eternal hope of being the one who wins the lottery, but 99% of people will still always be screwed when fighting for an item vs the non-farming users.
How ironic that a loot hunting game works this way, even considering that it's supposed to be the best out there.
PRO tip for Blizzard: next time you make a game based around an AH, make sure people can't continuosly exploit it in every possible way, it makes the game bad for the honest players.
