At lvl 30, I have:
Mind Wrack - 6
Lurch - 1
Inner Focus - 6
Amplify Pain - 6
Sympathetic Anguish - 4
Precision - 6

Was kinda bummed to drop Neural Shock for Precision, but may figure try to out how to put a couple back into it.

With Chromaweave gear, the plat rifle and the Crit implant, I have 19 crit unbuffed, and 79 buffed with Precision. Mows down baddies. However, a drawback is that you become an aggro machine
