really but imoDid I said that her pool is smaller than others? NO. They fought Madara even after Tsunade recived chakra from Dan which proves that they still have enough chakra to fight back. I don't remember Tsunade restoring anyone besides Gaara and Onoki.Iam not trying to prove that her pool is smaller.Pools of other kages are not as small as you guys are thinking ,As far as chakra pool arguemnt goes Tsunade don't recive any credit for restoring kages as they were fighting even b4 Tsunade which puts them on equal grounds.
tsunade heals which mean
her chakra reserve depletes
others reserve increase
they were fighting before tsunde means they were more out of chakra
thus tsunade heals them
her chakra reserve would have depleted more
