I look at other DH with 275k DPS and what seems to be to be similar stats.
My CH is 52.5%, CHD with a one socket manti is 404%, 494 with a lesser DPS two socket. APS 1.77, Dex 2968. I have a Inna belt and a WHour (gives me a little bit more DPS - but not much) - this lets me do attack speed of +45% with the witching hour.
Manti 1 - 1339, 1 socket, 86 CD
Manti 2 - 1125, 2 socket, 73 CD
What am I doing wrong? I look at other profiles and they have similar bow and much higher DPS (without SAim or SS).
