I would prefer if pvp worked like this-
-you challenge a real person within the top 10
-you get 1 attempt to take rank 1per day
-if you win slot 1, anyone within top 5 can challenge you once per day and you have five minutes to accept the fight or the ai fights for you
-you can change teams as defender and the attacker is locked in when they challenge
-a defender is safe in rank 1 for the first 23 hours after victory.
