Eh, my problem had more to do with the fact that I have a knack for quickly identifying ridiculously powerful builds, a fairly predictable side effect of playing too much WoW and too many RPGs in general. Basically, I saw Brilliance and said "Welp that's overpowered," and went for that and Pistols with a dip into Stealth for Shadow Operative. After that the game was basically just an orgy of cooldowns and virtual auto-kills. I suppose it's my own damn fault though, in a way.
