The aetherial gear was nice, they had them in diadem... it sucked... I got a healer top with +6 piety, +115 Spell Speed and +15 critical... and there's no way of knowing you would ever get the perfect stat set up. (the +6 piety was so bad it was like why even....)
It would work as maybe levelling gear, like how it was in 2.0. When levelling the stats weren't as big a issue. At 70, doing savage, not really.
