They should have added Auction House, so people can farm good gear for other classes and try to sell it, that could have been a small placeholder till other content comes out. Miss me with that trading through chat BS, especially on consoles with no MK chat support.
Now this is gonna be controversial, but im sad that there isnt real money auction house, didnt get to enjoy that in D3 too. Yeah P2W sucks (but kinda w/e in a diablo game), but if i can make money by playing a game, hell yeah i will take that.
