Shaman PvP

Hey everybody, first time poster long time lurker. I have been leveling up some shamans currently with a paladin. I took them all into an AB today just to see what i could do and i got pretty stomped on. Now 2 of the shamans have no totems to speak of because i have been boosting them through the last 15 levels or so. While leveling ive had no problems with targeting or things dying at all. It just seems like i kinda go rolled on or maybe i was just expecting too much. Anyone with tips or anything like that on how they pwn in bg's id appreciate it. Thanx
