Even assuming all jobs had equal impact, BLM pre-7.2 would have a lower pickrate because it is way harder to achieve that impact with and way more work. Statistically that makes BLM an unreliable pick for PF.

The stats below PCT are irrelevant, because anyone who wasn't picking PCT as their caster was playing very off-meta. Statistically irrelevant thing to bring up.

But again, like I said, if nothing changed other than the game being perfectly balanced for all dps, BLM would have had a far lower pickrate because they are just harder to achieve that impact with. It was inevitable that they were going to change it, and it's foolish to think otherwise. Especially when it is related to a job fantasy as amazing as BLM is. Every other caster is corny in comparison to BLM thematically.
