I can agree with this... I don't see how Sasuke would lose his chakra levels from the last, if anything Gadien and buruto movie shows his chakra is increasing from the use of dimension swapping and humanoid susanoo.
Well, the dimension swapping doesn't mean anything if he can't use it (which remains to be seen). I don't think this'll be the same susanoo that Sasuke used against Naruto. For instance, the fact that it looks humanoid might be because Rikkudo Kurama is inside of it (and possibly the other bijus are being used). Basically, they're replicating Sasuke's biju susanoo (although more powerful). That being said, Sasuke has to have some OP combination in some regard if he's equal to Naruto, who can use the Ashura avatar.
And of course, Madara fans are getting mad. Looks like I'm going to have to re-establish why Naruto and Sasuke are stronger than him, and why the commonly used arguments used for Madara are wrong.
