Thanks for the tips.
I haven't died 20 times on anything, in any game like this, in years (and this is a bottleneck moment, blocking the progression of your character and more game content.) I started playing as a Sith Inquisitor, and now I'm enjoying that more.
Forget nerfing. I know they want the stories to have climactic moments and battles, and a boss should be hard, but I can definitely say a boss like this should not be "bottlenecking," and all the truly hard bosses I've faced are bottlenecking. I.E., I'd go to Tatooine but all the quests are blocked until I beat this fellow.
Why can't I take non-main-story related sidequests on Tatooine?
According to this thread, there's people 1/1ing this boss, though, and I've never played a hotkey-style MMO, so maybe I suck. Additional caveat: I was so incompetent for most of my boss fights with this guy, I had several skills not-unlocked (though they're not skills particularly useful to him, and I was definitely attempting to interrupt with force kick and stasis, and still dying reliably.)
