Are role actions a nerf?

[Leiloni]

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 this is what Ethers are for.

And I don't want to rely on other players who may or may not do what they should to manage my own MP on my healers. I want to rely on my own personal skill for my MP management. Anything additional like a BRD song was always just a benefit but not required.
