@Greg:
As far as his daily health is concerned, aside from the cigs, I assure you, he is 110% fine.
So I guess people can feel free to complain about the breakes without others going "Be considerative! The man is sick!!!" :ninja:

@Enzeru:
So it makes more sense to you that Soldier-san taught her how to dodge and run away instead of teaching her CoO (the logical choice in this case)? Sure, whatever makes you happy, buddy.
And when was Thunder Soldier confirmed a CoO user, again?
The only reason why people consider Rebecca to be a CoO user is because Luffy guessed so, but Luffy said that it was 'probably' Haki based on the comment of someone else about Rebecca never being hit. He didn't even saw she fighting at all, it was just a wild guess and that makes perfect sense since that's how Luffy dodges attackes and that's how his previous enemies (like Enel) could dodge all of his attacks.
But just because Luffy made that wild guess, that makes perfect sense for him based on his experience, doesn't mean he is right. From what we know - and saw from her training - it's the Riku family fighting style that is based on observing and dodging. It could be Haki as well, but is still faaaar from confirmed. So far nothing says they can use CoO, much less are extraordinary users of it.
