My main is a Sorc and they aren't bad. Not great, but not terrible. Mercs/Commandos on the other hand are just horrendous. Go play a ranked WZ for about a week and tell us if you haven't thought about deleting him multiple times. No offense, but the PVE server thing doesn't hold a lot of credibility.
I had a merc with Augmented Obroan and he doesn't even hold a stick to my lesser geared Sorcerer.
