So just with uniques equipped it seems I can reliably reach 300k dps with poacher's mark, but that's NOT including periodic Impaler procs (extremely cheap way to add damage), Phase Run for the vaal skill, ancestral totem buffs, corrosion removing enemy dodge/armor... and the 20 second 60% more damage buff you get from culling a rare/unique.
Looks good to me for a noob league start build idk. I've done Cleave in the past with stuff like Actum and Blitz charges and it was decent. Seems like an acceptable mapping build now, I'll probably try focusing Blight.
