It seems that all the current genin/chuunin need to have a bloodline/bloodlimit to be considered strong. It seems that you can't be a genius without a bloodline for example Neji and Sasuke. Most people think that because the other characters don't have bloodlines they can never become Uberly powerfull. But the thing is the Sannins and the 3rd Hokage didn't have bloodlines and they are still extremely powerfull. So if it is possible to be considered a genius even if you don't have an advanced bloodline, why aren't there any in the show?
