I'm running my 5 shaman on a new team every week. Right now staying alive more than 3 seconds is lucky. My goal is run 10 games a week until I get all the blue set. In the mean time I am getting non set epics. Once I get them fully geared I will try a healer +4. Right now my highest resil guy has 500. Next week I will have the pants and should get another epic ring or cloak. When they release the rewards for wintersgrasp I will have the helm and boots. I thought they fixed team matching with wotlk. Today I played a team that was 1650 ranked 64th on the battlegroup last week and I only had a 1375 team rating. I still think the matching system sucks ass. Until I can gear fully with 80 pvp gear I am not going to try at all in arena.
