After I started playing with Hardcore characters, the game instantly got much better for me. Every boss run to find more itens count, no mistakes allowed.
But I agree RMAH sucks, and item drop rate is just too low.
Personally I dont even care about PvP... only if it is a superb multiplayer expercience like, for exemple, Battlefield 1942 was by the time.
