1st off, judging by your gears, I think you're are still lacking crit chance even with Archery passive. You don't really have to worry about Attack speed since you are using Calamity. Try to concentrate ur ring's and amulet on CC & CD. CD because you are lacking as your calamity has no socket. Hp is ok but your resist is quite low. This one you might have to spend a bit to get AR gears. The tricky part is maintaining your hp but having more resist, CD and CC. This is going to cost you. I think it's because you build your DH around HP, now to maintain it by changing gears, it's very expensive. Honestly, if you're running mp0-1, at 45k hp with 400resist and 4k armor is good enough. 50k + is normally what we look at running mp3 and above. You can sacrifise some vit to gain dps and resist if your running lower mp. Pretty balancy build but get more CC.

I can't wait for patch 1.0.8 cuz they better fix the range classes esp DH.

Problem now is at high MP, all classes becomes melee fighters.
