can't say i'm a big fan of eyes having so much power, i think that should have stopped with the base byakugan and copy sharingan... that said the powers are pretty cool, albeit ridiculous.
Well maybe you could say it offers more insight on ninjutsu. I mean Nagato pulled off some things that seemed pretty abnormal compared to regular ninjutsu standards even when disregarding the paths. I think the 5 elements fit into that category too.
