Are role actions a nerf?

I feel like BLMs will probably end up the real mana batteries. Umbral Ice is just a very potent mana restoring mechanic. 20% MP would be recovered in a tick of Umbral Ice III.

If the new BLM rotation is going to be as tight as it is now, I don't want to have to have to also monitor healers MP, and suddenly give 20% of my MP to a healer so they can rez/heal someone etc... in a split second to avoid a wipe. I thought that is what Ethers are for.
