So far, only those who are in a village can challenge their leader. I believe this should be moved to Organization's as well. Like a village Organizations are ran by the leader and he/she should be able to get challenged for their position. Even in anime an example is Orochimaru's group. He got succeeded by Kabuto, not necesarilly by a challenge but it does occur. The mist swordsmen is basically a challenge, Kisame's sword liked Bee better, its like a challenge over the swords loyalty. The main point of the matter is that this little change would be surely beneficial. Thanks.
