You need to stop nerfing one or two things on a build because you will just gut the build and something else will arise. All you do is nerf one thing half the time so people just stop using it completely but you don't think about or suggest what they should play instead. You must think about the consequence of what you are doing and what builds will take over if you gut things.
This classes need heavily tweaking across all skills and traits, play with the numbers and bring them down overall so a new meta doesn't take over. Why not poll what builds people want and work your balancing around making those favourite builds meta like d/p theif and portal mesmer for example, there is no reason why they can't be part of the meta. You need to find 3 builds for each class that people like to play and make making those builds good your concern not just nerfing stuff so its a constant loop of killing a couple of things and the whole meta changes into some new cancer.
Talk to the best players of the game as well why don't you do this? They would all like to have something to say but you never communicate with them at all, never replying to them or trying. I feel all you do is really show a face when the going gets rough, really need to start doing more to communicate with the better players of this game, the veterans know the game and pvp better than anyone and know what is good for making it a healthy game mode where we have balance across the board from builds themselves to how they fit into compositions.
