Watching Eric Musco, and the backpeddling devs chosen to represent the developers on the PTS, it's quite apparent that they intend the classes to play as backpeddling noobs who don't know what a White bar is.
Which effectively means, the one person who manages all class balance, I think is Austen Peckerpeck or whatever, is a backpeddling noob who only plays FOTM classes and plays them so poorly thus insulates them from any nerfs while causing more nerfs to classes like the Powertech.
So honestly we should look at this with a glass half full sort of situation, thank god they don't balance regularly or at all, otherwise the overpowered classes would be even more powerful and the nerfed ones even more nerfed.
