You can win rare weapons and shards in pvp, though. Nymphs/marks are turned into relics, and everything is turned into its unupgraded form. Same thing with the arena. (and pvp1) I've heard the money is good in pvp1/2 now, but I haven't played it in a long time because of all the newbies with weak decks there; I just didn't find it very much fun.
