Dinging 85 soon (would've dinged a few days ago if I didn't get distracted by other pursuits), and I'm going to be looking at i312 pieces in a couple of slots. I have enough JP to buy a piece, but I also have enough HP to get a PVP piece as well (or two? I can't find the costs on Wowhead). Is it ok to buy a PVP piece or two to PVE in with the understanding that I'll be upgrading to a PVE piece as soon as I can, or am I risking shunning/booting if I do so? I can't imagine it'd be an issue, but the userbase has disappointed me before ...
EDIT: To be more specific with my concern, since you require a base ilvl to do some dungeons, putting on a non-ideal PVP piece could be considered just trying to raise my ilvl to qualify for the dungeon
