Anyone have any insight?

I was set on a rogue but since doing the 10-19 warfronts it seems my rogue (assasing/riftstalker) spends most of his time snared, rooted or simply trying to catch players. Not much fun.

I have a level 12 Pyro on the other hand who is just blowing stuff up ....and not dying much at all.

How does it change towards the higher levels...anyone have insight?
