Kakashi vs Zabuza for me

Can you really consider Kakashi vs Itachi a fight considering all itachi did was put Kakashi under Genjutsu

I'm only realizing now how goated pre-shippuden Naruto was. We got one or two new kekkei genkai every season, a whole new cast of characters, and summoning jutsu was actually a cool and relevant thing.
