While I agree the balance between 55-59s and the rest is pretty bad, I think it's almost as much about expectations as anything else. I've been playing my jugg since lvl 30 (now 46) in pvp as often as the queue allows, and still having fun. I just stick with the necessary, but less glamorous jobs like guarding nodes, being a taunt/guardbot, peeling/cc or harassing healers. I don't expect to kill much or do a lot of damage, but I can still be somewhat useful and have fun while doing it. Fixing the bolster weirdness would probably be the best solution to providing a balance between a level playing field and reasonably fast queues.
