BLM is one of the few whose attack potencies either match healing potencies or bear far less difference. Fire 4 is 2500, Cure 1 is the same. But most DPS combo enders are 1250/1500 at the least, 1750 with ammo for a MCH. Even Foul comes in at 4500, 500 less than a Cure 2.

While I understand coordinated burst damage in the Feast is why things are the way they are, I again look to the Soaring buff as the balance tipper. A healer doesn't really have to do anything to gain such a strong buff, and if the team runs multiple healers and one DPS, they can just powerheal the one and build up a ridiculous buff from the DPS' efforts. Not sure Soaring is kept if you switch jobs either, but if it is, that makes it even more ridiculous.
