Ok Sasuke was with him for a very long time. The only thing I see Sasuke using is Chidori and his Sharingan Techs. Was his training with him pointless. Oro used a lot of cool jutsus. You would think he would teach Sasuke these techs. The only time he used Oro jutsus is when he absorbed him. What a waste of time. Does anybody have an opinion on this.
