Found a couple of upgrades. bumped me from 150k to 190k....170k unbuffed.
I can mow down MP4 with crazy speed only real snag up is the Act 3 keyboss....I hate him so much.
It really seems like the Illusions that the Act 3 dude splits into all do full damage with their AOE slow+dread corpse attacks. It doesn't help that the entire area is covered as well.
