Some views on DPS balance that everyone cares about

[ReiMakoto]

Thats the part you actually have wrong. It should read this...

BLM: Poor mobility, without team assistance and resurrection, but in exchange for high firepower.
SMN: Good mobility, with LOW team support but has resurrection, but Moderate firepower. (This is what those things I linked actually showed, it does not have "high" firepower except in High Mobility situations where other jobs CAN'T use their actual high firepower)
RDM: Moderate mobility (exactly between BLM and SMN), with Moderate team support, including Buffs (Embolden), Dual Casted Heals, Dual Casted Raises, medium firepower.

You overstated Summoner and understated Red Mage.

This is untrue summoner does have high firepower, when you reach 90+% classes are not being harmed by movement at all cos, everything has near 100% uptime and mobility, any high end black mage parse has used instant casts to be mobile exactly where they need to be, SMNs numbers are just overtuned.

This is why in a fight like ramuh, even at 99th percentile they are only just beaten by black mage, even though ramuh has basically 100% uptime on all classes and no adds to pad on
