I have been told that lock/shaman is a good combo but I'm having a very difficult time finding a lock who knows how to dps and chain fear while knowing how to avoid damage (shield/teleport). I cannot say im so great myself. I've only gotten to 1800 rating. I've also tried with a warrior but did worse and he was much more experienced and geared than any lock I was with.
What are other viable combination's since I'm about out of luck for my 2's team.
