So i have an idea what if two students can switch teachers for example let's say scorps is teaching X in fire and caliburn is teaching me in water. X and I are friends so we decide to switch teachers so that we get more training.
-You can only have two buddies.
-When you switch with someone you have to write all the jutsu's that your buddy reached and follow the same rules that were imposed by the teacher on your friend.
_____________________________________________________
The other suggestion is for senseis and sempais let's take scorps and caliburn and we consider cali as the sensei. Let's say scorps accepted to train me in fire so once i finish B rank Cali takes scorps place and continues the training this will help students have mastery over elements and will shorten the training time. So sempais will teach B rank and sensei's will take over and continue A ranks S rank and forbidden.
