PVP and Player/Dragon Levels
I think there should be a few options in PVP:
1) to elect to be matched against similar level dragons/players
2) to elect to be matched against a specific player (by name or from the friends list)
Also, it's very important that the player level/dragon level of the opponent(s) be readily visible BEFORE the round starts -- so an election can be made to quit before you get clobbered in one hit.
BTW< I think levels should readily be visible in Boss rounds too from the main room -- so you can click on a room with like level ppl.
