since i mostly boost anyway, i started off with the cloth heirlooms (since all classes can wear them) even tho the stats aren't really for them, the only reason i got them is for the xp bonus anyway, over the past month, i've managed to get clothx5 leatherx5 and platex5 jst need to get the mail and i'll have them all. got hat and cloak from guild vendor, and shouders and chest from pvp vendor (except for plate which i got with jps) i know some are better than others, i jst didn't take the time to fig out which ones. i'm not a big pvper anywya, but the other guys in the zerg are slowy getting me into it (most of them lvl exclusively through battlegrounds)
