Yeah, I agree with this.
I can run into a Warzone, run into a level 40-50 (Myself not being very far off at 34, so I am guilty of this too) and I get either stomped by them, or the level 10s-29s I can totally annihilate. This really does need to be bracketed, because no matter what you do, more skills, or armor bonuses, or just skill with the class is going to dominate the other players.
