dude how many resists you have? And your life sustain is kinda low.. need LS around 5.5 and above and if possible, get LOH as well.. so u can have much comfort in dealing with mobs.
We all know that MP10 mobs and elites are now harder to kill thus we need some form of life sustaining capabilities regardless of DPS level.
I have like 450 AR now. Didn't see the need for more as elite is down in sec as of now.. This might be one option, upgraded the main hand with LS while decreasing some dps. Not quite sure if this is the best option going forward.
It's what I did also
I had to give up a lot of my pure DPS stuff to get more resists and more sustain since as you mention, the big guys aren't melting like they do now.
Seems to be working OK since I get 6% LS on ~140k DPS with 4 Spirit Regen/s even without mantra or passives. Had to buff up the HP too. 30k HP wasn't cutting it in MP10.
