Well, what happens is Act 1 Inferno is still ok for most people. But when you go to Act 2, suddenly the game becomes insanely hard. This makes no sense because Act 2 should be slightly harder but not too much. Then Act 3 again slightly more harder than Act 2 and so on. So the will tweak to make the transition more smooth from Act 1 to Act 4. So maybe Act 2 will get more nerf so that its closer to Act 1, and Act 3 lesser nerf.
The plan is until local time 4am.

Maybe finish earlier, maybe later, have to wait and see.
