19 minutes of SMG.
Used SMG and three occulomotors on Crimson.In retrospect I should have used optic as well.
It turns out power stat doesn't affect ballistics at all. Avalon at 590/81% and 1084/81% both take about 100 bullets to down easy Terminatrix.
Now to figure out how the damage taken percentage works. Agility is the only factor
