those are the pieces that all those people got who jumped clans a few months back. I see this everyday in the DZ. The pieces are legit, the issue is they have never dropped in the game other than those instances with the clan vendor. Its why the DZ sucks right now because you have a subset of players who all have these god roll pieces that have never been available to anyone but the people who jumped clans. With the TTK low in this game, that extra armor is almost an instant win.
