So is there any PvE tier bonuses that would work out okay, pretty good, or even broken in PvP, assuming you still have a high PvP Power percentage down 2 or 4 PvP gear pieces, i.e. Full Prideful on all the other gear pieces? In my case, I was looking at the Priest healing T16 2-piece, and I would think that it would work for a Holy Priest. (Synergy with the PvP 2-piece bonus and Serendipity) Or would the loss of PvP power and the 4-piece bonus (5 second Chakra CD, important to get Chastises off) makes it not worth it in the end?

I do know that some other PvE gear (i.e. Legendary Meta, Legendary Cloak, some trinkets) were nerfed specifically in PvP because they were too strong.
