The game was just ridiculously overnerfed. You are meant to spend time farming in Act 1, the difference now is that by the time you get to Act 4 you will be able to take 4-5 "wind-up" style avoidable attacks, kill yellow and blue packs together and have no challenge in the game at all.
They just broke the game by making inferno too easy, not too hard.
