Dojutsu ruined Naruto. When it was just the Byakugan and the Sharingan, that was one thing as they were just powers that actually involved eyes.
Then came the Magnekyo Sharingan, and stupid crap like Susanoo. You know, magic armor being tied to eyes makes sense right?
And then finally came the stupidest fucking power, the Rinnegan with its twenty different powers, none of them actually related to usage of eyes at all.
