Lol, I always wait until everyone's done choosing and if there is someone who needs consistently I will start needing too and I'm severely lucky so I always get it.
PvE and PvP should be entirely separate entities the way this game is setup. If you can have the armor from PvP in PvE, the stats need to be nerfed big time, completely unfair to those to grind in Dungeons for good armor as opposed to people who farm PvP all day by afk'ing in the match.
