Lmao what kind of argument is this?
Paramecia users waste their stamina when they're using their powers we've had it several times in the story.
Doflamingo always had a poker face even when he can barely stay on the feet as Luffy noted.
There's literally no reason why Doflamingo's ability isn't taking away from his stamina while it does with Kaido.
