Blizzard struggle 24/7 with PVE items in PVP but it's obvious that WOW is PVE game and PVP is just small activity like pet battles etc which means nothing. And it's ok when PVE items is involved in PVP. This attracts more players to this activity. But it's absolutly another story with PVP items in PVE. It's not ok when activity like PVP or pet battles give advantage in PVE. According to bluepost you can faceroll 2-3 heroicraid-quality items every week in PVP and even mythic-quality if you take this activity seriously...
