Dear Healers who don't DPS

[Cynfael]

Hall of the novice is the only vaild argument here as harsh as it sounds, because all the rest whether or not it is used as an argument for or against healer dealing dmg, is just an dialog an the opinion of an NPC and NOT Square Enix.

What.

As others have pointed out, NPC AI and dialog are implemented by SE.

Further, yet again, the opinion of any SE employee, up to and including Yoshi-P, is irrelevant to any gameplay discussion. What they actually code into the game is what affects how we play.
