I've leveled up every DPS job. I know I've played them non-optimally (hit combos, build resource, mash everything else on cooldown or when it lights up); I've likely even played some of them outright badly. Between cast times and resource management, BLM is the only one where I've found myself in a definite fail states (Enochian dropped, at zero MP but can't get myself into Umbral Ice without MP…).

Merely doing less damage than optimal doesn't teach you anything in a game that doesn't quantify your DPS for you and where "real" DPS checks are limited to certain content.
True. It doesn't excuse Glarespam though. If I wanted my kit to be as foolproof as possible, I'd probably do something like the bar doesn't drop if you cast the wrong element spell but it doesn't increase it either.
