Even with insanely high defenses, only certain builds with the best equips can handle mp7 and up. Blizz's philosophy for the game has been to promote build diversity without forcing players to play a certain way to overcome challenging content.
All this change does is reduce the need to play a specific way. I for one see no problem with this move. Plus, this isn't a change because of players bitching and moaning about how hard higher mp levels are, it was because of a bug! That, you could say is Blizz's fault.
Don't get me wrong, a lot of the players who have spent millions on items to beat higher mp levels will be upset that they won't need that gear as much now, but that group of people is a small minority. Even so, that specific minority of people will still have the pvp patch to look forward to : )
are you kiding me? I have crap gear and I could stand in molten and jump through arcane beams like they're nothing in MP6. Please don't complain about the haves vs the have-nots.
On the fact that it's a bug (apparently). If that's the case, why aren't they fixing it in normal as well? Reading between the lines it sounds like they're throwing out "herp derp, it's a bug" just to appease the people wanting a harder game. If it's really a bug, why don't they fix the bug instead of just nerfing damage across the board? It doesn't sound like a bug fix to me....
