Well all the transformations and juubi absortion bs took way less than I expected. Thats the best I can get from this last chapters. Anyway the powerups are getting ridicule. 5 kages, edo tensei kages, naruto and sasuke and they still cant get close to him.
I think that it was only to show that Naruto is clever when fighting. Minato needs to have marks (his chakra) or to touch the targets to use his teleport so naruto used his kyubi shroud to touch his father and Sasuke so he could TP them. I dont read anything else into it.
