After spending the last hour drinking my morning coffee and perusing this forum, I was going to post a much more verbose version of this. Instead, I can give you a hearty +1 for yours. Your sig is similarly accurate, +1 there as well.
PVP is a completely different skillset from PVE. There are plenty of MMO'ers who are merely average at PVE (hint to general public: you're probably not as good as you think); throw in the additional complexity of the PVP domain and the issue is amplified many-fold.
There will always be an immense amount of QQ in any game's PVP forums. An overwhelming majority of it centers around class balance and originates from the mediocre, the unskilled, or the inexperienced/clueless.

My only two requests for near-term changes to SWTOR PVP would be as follows:
1) Change Ilum to a Warhammer-esque RVR mechanic, where every point is locked down except for the one "contested" objective. This objective moves towards the enemy base as points get captured. Severely limit Valor gains (i.e. give no bonus or quest credit) when fighting reasonably far away from the contested objective.
2) Revamp the Resolve/CC mechanics. This is a much more difficult fix to implement, but I feel that something has to be done or else the "texture" of a PVP match will continue to feel just a little bit frustrating for most people, even skilled players. Legitimate frustration leads to lack of fun, which leads to lack of interest, which leads to lack of subs.
