Madara and Obito are defated. Then Sasuke shows up and takes over control of the Juubi. Shit goes crazy.
Truly boring battle. Why do the shinobi think they can beat the Juubi with that? It takes one attack and all those random ninjas would be dead.
Also, it makes no sense to have Shikamaru´s dad in charge of the attack coordination and not Shikamaru himself. Unless his dead is about to find death.
