Like this- i wouldn't give two characters the same power in the same arc (one Juubi Jin, Madara since he is the final villain/the big guy).
- give all the Hokage's equal screen time to show off their power properly (why would i bring them back if not to fight).
- less TNJ.
- wouldn't make the Juubi's Jin's defeat look this ridiculous.
- and finally, i wouldn't pull off stuff like the Wireless Susanoo/late SM.
