Are role actions a nerf?

[Vexander]

Think of it as an ability that lets Black Mages, Red Mages and Summoners replace Bards and Machinists.

Also lets you pay the Healer back for Resing you and you can both be annoyed at the dps who keep dying.

Well, replace them as far as MP is concerned, not TP. That said, 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.
