I wonder will there be a arena type thing implemented, like prolly where the tabs are, you could add one that says arena. There can be 3 arenas so not everyone has to wait for one fight to finish, and when you challenge someone, a popup box says "-insert nam e here- has challenged you! Do you wish to accept?" and you can say yes or no. Once you accept the challenge you get tele'd to the arena. Idk, just seems like a easier way to challenge people, and if a kage or anbu tele's to someone during an arena match, that person is disqualified. I don't know how long it would take to code but and replies are appreciated.
And also there should be a way to spectate the arena match if one would like to. A fixed camera mode for everyone that wants to watch which is at the center of the arena
