As a player that's bounced back and forth between CoX and Wow for the past 2-3 years, and an avid PvPer on both, I can say with certainty that this game is not alone in it's PvP woes.
Many people consider WoW to be "more balanced" than alot of games, but really it faces the same problems that are described in this thread and others in the forums. There are "perfect builds" for pvp, there are even classes(or ATs) which are better than others, both for 1v1 and team encounters(as the top ranked arena teams clearly show).
And to top it all off, the WoW devs don't respond or acknowledge even the best written and well-thought posts on their WoW forums either.
The simple truth is that today's players are not simple at all. We are intelligent, intuitive, experienced, and informed. Many of us have grown up with video games of all types, and been part of the evolution of PvP since the days of Pong(for chrissake!). And ignoring the vocalization of that experience in relatively calm and intellgent threads such as this is akin to not accepting a twenty dollar bill because it came crumpled and worn from being in your friend's pocket instead of in the form of a printed paycheck with your company's logo stamped all over it!
Dismissing player feedback from forums because "it doesn't represent the majority of the player base" is pure idiocy. If anything, the players posting on the forums are the ones your should be listening to because they're the ones that actually care enough, and are (computer)-literate enough, to post in the first place!
The biggest mistake of conventional MMO developers is assuming that they know what players want more than the players themselves. That mode of thinking will not last much longer in today's competative gaming enviornment.
Talk to us. We're NOT stupid, we WILL understand when you say no if you bother to explain it to us.
