So I ran operative thru to level 16. I wound up absolutely in love with the feel of the class when I was playing agent... EXCEPT for the cover mechanic. Being forced to stay in place all the time drove me apeshit. Switching to Operative made me very happy... I need to do some examination of the operative-vs-sniper endgame dps tho'... I'm a little worried that because it's a hybrid, operative will suffer a dps tax, and thus suck. I'm likely to go powertech BH if I don't go Operative, tho'. I wish I'd had more time - I would run that through a bit to see how I liked it.
Pvp as operative was fun-but-weak at low levels. Before melee get many snares and evasion talents, life is tough in pvp. There's no diminishing returns on CC chains, either... was a bit of a rude awakening when I figured that out

The storyline of the game was freaking awesome, and the flashpoints made the three of us laugh a bunch at eachothers' responses - was great. Very nicely executed flavor.
Overally pleased. Beta had obvious beta issues that we hope get fixed. Some serious balance issues in crafting form what I could tell (slicing seems way too good, for example). That stuff still has time to get fixed, though we're close to R-day.
I guess I shouldn't worry so much and just play what I like, since, after all, I'm in Japan so I won't be raiding or anything
