..coordinating attacks as a team?
You've seen a small set of teamwork, such as Pain vs Jiraiya and the filler Pain vs Utakata.
What if he focused more on that, especially against Konoha?
Like Deva Path using Shinra Tensei on someone straight into Human Path, where he removes the soul.
Or someone like Asura Path using a suicide attack, for Naraka Path in the back to revive him.
