Buff up the potions or implement a new one

Besides, as a BLM, you should really only use an X-Ether or Hi-Elixir to set up a second or third Flare, or as a save from a bad rotation, so they gain little advantage. SCH and SMN have Aetherflow... enough said. That leaves WHM as the greatest benefactor, but that's still not much.

Don't underestimate 400-500 MP as a healer. If I have to raise a couple times, or if I happen to die at all, that X-Ether sustains me for a bit until my Shroud/Aetherflow comes off CD. You may not think it's much, given that it's roughly 2-4 GCDs worth of spells depending on what you use, but I've saved parties with a perfectly timed X-Ether before. They aren't meant to be used regularly, IMO, but mainly for situational purposes. You can say BRD is better, but MP song is gradual, not a burst 500 MP back to me, which is much more useful in the short term.
