POW, I like your post. One think I really can't aggree on though:
The Oro's scroll being a rinnegan? Really?
The user of the Oro's scroll is supposed to have such a power that he will win the war. How would you win the war for sure with only a rinnegan? When there are so many rinnegans already in the field: the beasts, their jinchurikis, Tobi, madara, Nagato. Most are dead now but they weren't in the time the scroll was supposed to give the power to win the war.
No no no.
Something much more badass is coming up...
