If it was like that wizard city would turn into a world of WAR !
I agree with setokaiba. You could port to a friend in, say, Dragonspyre while you're only on Krok, and have a lvl 40 attack you and defeat you. While I admit PvP would be easier, you wouldn't go up in ranks, or get tickets. Like she said, Wizard101 would be a world of war.
