So I have most of the FoeStriker set, but when I was doing a dungeon today we were able to get a piece of the Acolyte set (I was the tank), I needed it because my next class will be a magic class. When I hit Greed it said I already had the a that piece of the set, and I don't. So can you only have one set? So either FoeStriker only or Acolyte only.
