hey :)
what power will you want get, what artifact ?
for me if this is REALLY artifact i would like to get "infinity ascendance" or each multistrike decrease all your cds by 1 sec :) ... for me this will be artifact.
weapon texture mhmm 2h mace @.@ Sulfuras, Hand of Ragnaros (but probably warrior gets it) or 1h mace + shield :P
