While I agree with your assumption that SE is too stuck in their ways to make the change, I do think we have to stop normalizing it.
There are able with a sufficient precision to balance all dps jobs within 2-3% and they choose not to do it for outdated reasons. Just look how all melees/PCT/BLM are well balanced, maybe a bit a fine tuning would be nice but overall solid job. And then there is a stupid "ranged tax" that doesn't apply to PCT and BLM for some reasons.
