Or what about the existence of Hunter Nins. Why didn't Konoha send out Hunter Nins for Sasuke? Why did Kishimoto even explain the purpose of Hunter Nins, if he wasn't going to use them. That's Kishimoto shitting on readers.
I guess that was to have a coherent universe...more detailled...and we might see them in action in some chapters who knows...
I hate guys that are disrespectful to autors...Dude, if you think you can do a better job then...DO IT !
