i think there should be more high leveled options, rebirth, sound, akat, and village special, are all good in their own way, but they're still kind of let downs considering the level requirements (village special, rebirth), and the requirements (only a 10% chance of joining sound) and the fact that everyone in the game who has joined akat said it sucked (bad jutsus, small training space, no missions, and always having to guard your money).

Also for rebirth i think they should be able to kepe their stats. Being level 1 in a new village isnt worth not being able to use all your good jutsus or dojutsus (in the event of uchiha or hyuuga) because all your stats are reset.
