I don't know if there's gonna be doujutsu in NinOnline. But, if there is I think there should be more than Sharingan, Byakuugan, and Rinnegan. I think it'd be cool if more obscure kekkai genkai were added. LIke Haku's which allowed here to make Ice and Kimmimaro's which allowed him to make Bones. Besides that I think that more doujutsu and kekkai genkai should be made aswell to go in addition to the anime/manga's kekkai genkai like stat enhancing kekkai genkai. I think this would be a great idea if the creators wanted to add in the tailed beasts. So they could have doujutsu and kekkai genkai to combat them. Anyway this has been a suggestion from some guy named Lance(its my name). B)
