"you brought dragoon because it buffed bard" yea well so ? i'm not saying you are wrong in that, but that only means bard in stormblood was op (potentially i would rather say the crit synergy meta was op, but thats a different discussion), that may very well be true, i just don't see what it adds to the discussion, bard in stormblood had a lot more going for it than just damage. also in your own example funnily enough you would have brought a dragoon to buff the "samurai numbers" pulling mch but thats also the point, dragoon was balanced around buffing 1 physical ranged while physical ranged where worthwhile on their own, that let to people realizing if you take 2 physical ranged the group dps reaches unexpected heights (which currently fflogs would actually attribute to the dragoon, you are basically arguing that dragoon got to strong by buffing the physical ranged).
also lets act like there where only 2 fights in the game, for simplicitys sake if nothing else. no one in their right mind expects any physical ranged to pull ahead of blackmage on voidwalker, but what you offer with "o12s was soooo melee unfriendly" is only the most extreme counter point, if samurai where equal in some "general movement level" fight to mch than that would end in samurai indeed falling behind in a melee unfriendly fight, it would however just as much mean a fight like voidwalker would still favor the melee. only saying "oh, but what if theres a melee unfriendly fight like o12s" is like the physical ranged complaining about the dps gap on voidwalker instead of the "all fights" metric
