Sasuke really shouldn't be able to do what he did. He should be practically on the brink of death considering he has used his chakra for the past 200+ chapters in constant battle. Hell, Nagato, who is a Uzumaki and has one of the largest chakra reserves in the manga, had to use almost all his chakra for one Chibaku Tensei, yet here is Sasuke who does 9... You can argue that Nagato was weaker because of the rods, but this sh*t here is ridiculous.
Every character is basically god now and chakra is quite meaningless. Kakashi, whose chakra reserves where always quite low, now basically can perform like 40 Kamui's and his chakra doesn't seem to end still... The manga doesn't have any semblance of logic anymore.
