Tired of Uchiha
While some Uchiha seem pretty koo, they are quite boring and predictable in most fights, except for Madara.
However, there were some many other OP KA users the could have been even more BA and who I really wish had the shine instead, as Kish could have really done something crazy with them.
Ex) Haku- there were so many possible techniques that his character couls have used, making him the most BA shinobi in the series.
The Spider Guy from the hidden sound, with some Spider SM haha
Guren (filler or not) I feel in love with her character and ability instantly, abd probably the strongest females shown in the show.
I'm just babbling and dreaming a bit, but these characters would have been more interesting and a few others I cant think of right now.
