Looking a little closer there's (obviously) some differences to the old lvl 50 version...one of the perks that stood out to me back then was the 30% from Bleedout and the 30% from Dark Resonance(only 15% now). It's not possible to get Bleedout and Cascading Power...at least not without sacrificing the Accuracy boost. It would be interesting to see the difference in swapping Cascading Power for Bleedout. I'm sure a more ambitious theorycrafter than I could figure out pretty quickly whether a 9% boost that's up ~60% of the time wins over a 30% boost to your bleeds that crit 30-40% of the time.
it isnt worth it, bleeds are 20% dmg, crit 30% of the time, and a 30% surge will increase the total dmg of a crit by about 15-20%. .2*.3*.2=1.2% .2*.3*.15=.9%. cascade is .09*.6=5.4%
