I don't farm Brayflox for myth not because my main is a Dragoon, but because I can't stand doing the same thing over and over again. I need variety!

Though, I should point out, my fastest ever Brayflox run was with a WAR tank, me as DRG, SCH, and SMN. Amazing DPS. And Dragoons can AoE! They just have to know how to position properly for Doom Spike and remember to use Invigorate.

I agree that the whole "play a different class" is a horrible response to this topic. Every party is viable for a speed run assuming everyone is sufficiently geared and knows how to optimize DPS rotations.
