If I'm not mistaken I think we got some pretty mixed messages on healing between the different community interviews Yoshida did for Endwalker no?
I remember one of the earlier ones being really quite disappointing (Mr Happy's?) whilst he opened up and actually gave some interesting answers in one of the later ones (Zepla?).
How accurate and true to the game said answers are are of course rather questionable. I can't fault what Yoshida's done for this game but it's been shown on several occasions over the years that he doesn't always correctly understand it's finer workings.
