Nope. But just because you can doesn't mean everyone can.
Looking at your gear, you are in fact a glass canon if you really play on MP10. If it works for you, it's fine, but don't expect that DiaBro will ever recommend people with your EHP to enter MP10. Same with your DPS (it's 285k, btw, and not 500k as you mentioned in your post).
Don't get me wrong - whatever works for you! I'm glad you're having fun on MP10, but for many people 250k EHP and 285k DPS is not fun on MP10, as it's hard to stay alive against most elite packs with these stats. And with every of these posts I'm worried about the impression it gives other players reading our forums.
Nah, it just depends on the build for the task at hand. With hota/rend i can stand in poison+desecrate+multible arcane beams and go hunt elites if i want to or do mp10 ubers (pretty pointlles at para 100).
Atm im running a ww build because i mostly farm trash with perma wotb (462k dps with this gear, got some gain dmg/lose ehp spare up to 537k buffed http://awesomescreen....com/0e41pydwc6 ) and skip elites because they are basically just a waste of time.
My guess is it puts me at mp7 beause my max life is pretty low and i can get one shot by some avoidable attacks but i tend to avoid these since they are avoidable o.O
