Quote from GalZoharSince 1.0.5 profile updates have been (very) slow. Just be patient.
1.0.4 38k HP was fine. 1.0.5 MP0 is much easier. No reason you should get 1-shot in MP0 with 38k HP. Worry about higher MP levels once you can kill anything in 1 sweep in MP0. If you're still dying with MP0 with 38k HP then it's not an HP problem,
I have been clearing mp3 without dying with ease. I cleared act3 quite fast on MP6 last night after upgrading my gear a bit (also without dying).
My current gear is:
1911str / 1106vit
73k dps unbuffed. (53.5% crit, 351% crit damage)
49k health with ~550 all resistances.
But MP6+ is ineficient, I just tried to see if I can do it. As for MP3 I could farm that quite fast even before I upgraded my gear, when i was with 50k dps and 49k hp :]
