Make Kakashi use his ninja dogs more, and develop more canine associated attacks. It's like he traded in his specialty with dogs for thunder, which to be honest has become pretty cliche.
I also wanted Kiba and Neji to get more attention.
yea... Kishi kinda trolled us with that one but what are you gonna do... and hey, maybe they will get back together considering Sasuke, Suigetsu, and Juugo are already together and Karin is about to break out of jail so yea!
