So remember when Nagato handled Bee and Naruto quite easy but suddenly Itachi this cowardly dog attacked him from behind.
Why did Itachi blocked the shared vision of Nagato and attacked AFTER?
EXACTLY, because Nagato would have blocked even Itachis technique with Shinra Tensei or Preta path for example if he did see it coming. but in this case Nagato is focused on all of them, his summonings are flying arround and are focused on all of them.
Nagato has full helath and mobility, he can use Gedo Mazo and all elements which he has mastered perfect in an age of 10! So imagine if Itachi, Bee and Naruto would have fought a 100% healthy nagato then.
