I think kishi wrote himself into a wall, he has been restricting powers and techniques for sometime now.
Rinnegan Obito:
Restricted his rinnegan because having him use it would of ended the war already.
Madara:
After madara has used his godly powers, He suddenly got the urge to use only tiajutsu and stand around with his susano'o.
Juubito:
So far, he has been restricted way too much, Logically, Juubito should be able to wipe out the entire field in less than a minute but wont happen for obvious reasons.
Kishi made the villains way too powerful and thus the reason why he keeps restricting their powers so the "good" guys have a chance.
Does this bother you?
