i have just farmed 5x full set of heirlooms to casters with trinkets + got helm and cloak.
Im thinking of starting either 4x ele sham + pala/war tank. or 5 mages.. I cant realy deside which one, im gonna buy 5 new accounts and get that new 1-80 recruit a friend system on them, so 5 mages would be ALOT easier with recruit.
