I was thinking when he reach the rank Chuunin he should be able to go into missions and when you go into the forest theres a section saying traning fthat you can spend your points on Health, CHakra, Attack, Defense,Money,Travels,Gems and stuff instead of spending it in the mission headquarters.
I think we should have a 3 man team with a Sensei that gets Missions from the HOkage (Admin's Decision)
More Dwelling Feutures like Eating, and Rooms like normal House rooms and More Villages.
After Misions you egt Experience and Money
I think it's dumb like when your chuunin Iruka says you graduated from the academy or like whn yor Jounin do you still have to go to the Ninja Academy.
