So, right now on the PTR you can upgrade your gear 2x for 250 valour per hit (woot!), and justice gear for 750 justice per. Checked out PVP gear and nada. No upgrade. Not sure if this is just because the PTR hasn't been updated, or if it's a real ongoing thing.
Patch notes make no mention of it. Is it possible this will only affect PVE gear from now on? I'm not sure how I feel about this. Well. Actually. No. I'll be pissed.
