I do not agree with every change that they made with the last patch. I think the repair bills are now a bit excessive. I died once on a Butcher run last night and my repair bill was 13k gold.
I have not tried Act 2 since the nerf, but the amount of QQ by some players is just ridiculous. There are people complaining that it is now too easy, AKA, they feel a little less special because their millions of gold worth of gear is not as needed as before.
People will whine just for the sake of whining. Most of the whiners are ranged classes. They were completely OP before, cruising through the game with 10k health because of broken OP glass cannon builds. Melee was incredibly broken. I was struggling through act 2 with 67k health and 450 plus resist all while buffed on my Barbarian. I am hoping that the changes alleviated this problem. The Demon Hunters are crying the most...WAHHHH you took away my attack speed...WAHHHH you nerfed Nether Tentacles. Shut the fuck up. Everyone knew those changes were coming. When a stat or an ability makes content trivial to certain classes, it is going to get the nerf bat. The smart ones have already moved on and found the next OP ability.
I will be glad to advance through Inferno. It is a nice change. Now they just need to fix the apparently broken Witch Doctor, which is a ranged class that still sucks ass.
Things are going to change a million times. Deal with it. What was nerfed today will be buffed tommorow.
