I couldn't agree more. I see the classes as difficulty settings, Sorc is easy mode, then I would say BH healing, and finally Operative. I personally love a challenge and I love how an Operative...operates.
Same with tanks, Powertech is easy mode, then Assassin, Finally the Juggernaut. The claseses are not broken, they just require a little more skill and the ability to read make sense of what your skills do.
Sure, things can and will be improved, but until then I don't see anything gamebreaking and as horrible as most people are making them out to be on the forums.
