My marksmanship sniper is in full blackhole setup (except belt is rakata, gloves/relic dreadguard, one relic from color crystals, every item has a purple +cunning augmentation)
Damage (primary) 1061 - 1158
Bonus Damage 623.2
99.70% accuracy (109.70% tech attacks)
41.87% crit change
78.48% crit multiplier
My dps hovers around 1,4k in an average hm ops boss fight.
No matter what i try, can't seem to get it higher, i see some people claiming 1,7k dps parses on dummy, but i just can't get it past where i am now for some reason.
Pretty much full 61, you should be doing ~1.7-1.8k, fully optimized raiders would put parses up at 2k. And yes you have too much crit, a little too much surge, pull a few crit modifications, 1 surge one, and put in some power.
