This is very simple. You either have enough damage to beat Ultimate enrage or you don't.
Have you seen footage of people killing Golden Bahamut? When he starts to channel the last Morn Afah and murders the party members one by one and everyone's scrambling to actually kill him?
The clears where as the final blow is dealt half the party has died?
This is how incredibly tight that enrage is.
I just looked up the difference in Paladin and Dark Knight damage for Deltascape on the max percentile, and it's around 50 dps. That's the difference between the two jobs played perfect (some favourable rng non-withstanding).
It's small enough that you can probably clear with either if mitigation isn't an issue.
Now try to convince me you can lose like 300+ raid dps and actually hope to beat that enrage.
You can't. That's why the dps comp for that fight is crucial.
(Please get a clue before posting nonsense that I fell compelled to clarify with a lengthy post -.-)
