I'm a mythic geared tank and pvp rarely. Since the current pvp gear only gets boosted up to 730/40 I don't see the point in buying any gear besides 2 trinks and a legendary ring replacement.
I did some rbgs the last time the weekly quest was up and I can't say I'd drop raid 2+4 for pvp 2+4 pc. Is there something large I'm missing or does the gear just exist for non raiders to have ~730 in pvp?
I'm sure another likely answer is it's for Ret and Holy. I'm not trying to pretend Prot is of any real use.
