You're awful pessimistic in the matter, jesus christ. We're not talking about winning shadowmournes. This is a basic cosmetic stuff I think everyone should have a chance at, no matter if you do PVP or PVE. Nobody will become OP if pve or pvp has a ever so slightly bigger chance to get this item.
This cosmetic stuff won't suddenly make some super dodging premades pop up like mushrooms in rain. It'll just maybe endorse more people to run BG's.
The horde is running dodging 15 man AV enabler *****raids allready even without the scrolls, that won't change.
The PVP side is as it has always been, with or without the scrolls. I just think they should add a low droprate to it so even we can get some during our action. Just as casual raiders have a chance at it atm. It's not like running a raid is something unbelievably hard and heroic...
This **** isn't rocket science. The PVP has its tides, either the allies are wrecking or the horde are running DK + 4 heals premades. That won't change!
Also, grow some balls for PVP. It's as good as the system allows it to be. We all wish battlegrounds could be an even fight with even gear and highly intellectual players who all know that you're a god and your tactics are the only true ones. Sadly, PVP consists of actual humans from which some are actually ******ed. That's life. Deal with it. Go play club peng...*cough* ...I mean PVE if you can't handle tougher moments.
