Well, I got a chance to play a bit yesterday in Act 2. I think it is easier, but it does not seem overly easy. Champion packs are still not really a pushover for someone in decent gear like myself. I actually like the way it is tuned now. What I dont like is the new repair bills. It makes dying a pain in the ass. Dying makes me frustrated enough that I dont want to play.
I think that the ideal setup for Inferno would be to have a Barbarian tank, and the rest of the group be very well geared DPS. Unfortunately, if the DPS is not very well geared, it seems to take forever to kill Champions and Elites. It becomes a question of what is better. Slowly going through Solo or hoping that the group you get is not terrible. Not to mention 50 percent of the groups I join seem to be afk or something. There is almost always someone sitting in town not responding to chat. It is fucking annoying.
So, overall, I like the nerf to difficulty. I hate the repair bill change and the changes to drop off of breakable items. I dont understand why you would nerf the amount of gold that drops and buff repair costs when most of the crap that drops is unsellable for any kind of decent price.
