Yeah, you're right I think.
I would of also liked to see it with other villians and perhaps even a mob type character (Juubi Clones, Zetsu) kill or injure someone who is constantly present in the plot, I just feel like it would add some realism.
Also, I wish there were actually some real, sustained injuries throughout the main plot. How is it possible that during 3 years of deadly missions and dangerous situations that no one thus far (besides kakashi since he got beat up pretty bad, and still extremely late in the main story) has been injured severely enough to have a visible defining scar, or lost a limb that forced them to take an entirely new approach to combat. Neji freaking got a impaled by a huge arrow, but has no scar from it somehow.
Just another thing that I feel is left out.
Reading, such a precious skill.
