Gem and enchant for a lot of stamina and resilience, especially on your main toon. I don't have a problem with damage output.. I have a problem with dying too fast for my potential healer to react. Also.. I've found that it's nice to have a few skilled friends go with you into BGs.. yesterday I played EOTS with a priest + mage.. and it was great.. we went 15-1 or so.. didn't die much. If you move around with your healer you will get to practice your combat skills with all the new spells a lot. Don't be afraid to hit big packs of enemies.. when you face ~10 enemies in a BG it's similar to facing 5 enemies in arena, so it's good practice.
