Yo ,I figured out how to use my ap idead ,each attack will have two numbers ap it requires and ap it requiresd to be dodged,all ninjas starts with 5 AP ,if you choose to be an assasin(AFTER you reach chuunin)you will get 1 ap and you gain 1 more AP after you rwach Jounin and one if you join ANBU ,become kage or sannin.Hunter will get 1000hp and medic 1000chakra instead of AP(IF you chooses to be ASSASIn you can no longer take Jounin exams or become Sannin or kage).CLose combat attacks would require 3Ap(AP determinates your speed,agility,control etc so some spells like Byakugan and sharingan will grant you AP bonuses...),so yopu will have 2 more AP wich isenough to dodge a physical attack(you need 2AP to dodge close combat attack),but if you will become tai jutsus specialist(Obtainable after you become Chuunin ,then you can choose to be Tai,nin or gen specialist wich will grant you some good bonuses to that type of jutsus ,you will gain 1 mastery point per rank after chuunin you gain so you can add more points on tai so your physical attacks might become stronger.Youc an add more than one point on your mastery),also you can choose 1 jutsu that will be your signature move wich will have good bonuses...
So much for now ,hope you like my idea...
