actually, if you pretend like hunters don't exist, the rest of the classes are balanced out pretty decently in this bracket. this warlock gimpage is a surprise to me. really don't know what they were thinking there.
it's also pretty mind-boggling that blizzard took the opportunity to re-design and re-balance the hunter class and instead used it to make them even more broken and game-ruining at low levels. seriously, from a business standpoint, it makes absolutely no sense to make one class godmode at low levels. new players will start playing, get absolutely annihilated by hunters, and be completely turned off from pvp. kind of an incredible gaffe on their part, especially when they put it all the "effort" to re-design the class to begin with.
