Yes. . .YES! I whole-heartedly agree with this thread. Eye doujutsu are now dumb and over powered. I prefer the nice three-tome sharingan which is still pretty powerful. Being able to predict your enemies movements, seeing chakra, enhanced physical strength. and the ability to copy any jutsu by watching the hand signs alone. The MS is just dumb, and the EMS, the ability to spam the MS, is even dumber.
The abilities of the MS are too powerful, it's almost something you could see in a fanfiction.
Amaterasu burns everything it touches and apparently there are no ways to put it out (Some characters can absorb it)
Tsukuyomi can just mind rape anyone in the right hands.
Kotoamatsukami. . .Seriously?
Kamui. . . Just wow. Kakashi's first reveal wasn't TOO bad, but now it's. . .The entire Hachabi?!
Izanagi has a considerable downside, and I could live with this jutsu.
Izanami JUST NO. Hate this asspull. Made what could have been a good/great fight terrible. . . Right after damn flashbacks too! What a great way to welcome us all back into the fight. .
I am a bit biased towards the Rinnegan, though. . But I agree, it's too OP. Especially when the user can use all the paths together. I'd realistically limit it to . . A few paths.
Animal Path - Not too bad, just the ability to summon people/strong summons.
Preta Path - Ability to absorb ninjutsu, a bit too OP and has no weakness other than Sage Chakra.
Deva Path - For when it was introduced, it's not too bad if you have intel on it.
Asura Path - Again, not that bad of a path. But when stacked with the Preta Path the user is too damn strong!
Naraka Path - Doesn't have too many combat uses, not too bad.
Human Path - Insta KO. . . Way too strong.
Outer Path - Makes death meaningless and worthless, both to the characters and the readers.
I'd only keep the Deva, Animal , and Asura Path personally. . Not even allow the user to gain all five chakra types.
Senju DNA (Or more of Hashirama's) makes no sense and annoys me too. .
Though, I feel like another problem is that other kekkei genkai get no attention and are ignored. Haku's bloodline seems pretty powerful and versitile. Could bring back a character with that one, so what if they were all slaughtered? So where the Uchiha and how many characters have the Sharingan? Shikotsumyaku is another cool kekkei genkai, same with the explosion release (Needs to be toned back a bit, it's also pretty OP).
Gold release, The Iron sand, magnate release, lava and boil release. . The Byakugan could have gotten some attention from Neji, he was said to be a genius. .
