Are role actions a nerf?

[Fawkes]

Good thing we can change Cross-Class in the middle of a dungeon...

Besides, having Esuna as a Cross-role has the hidden benefit of replacing it with something more useful if the duty you're in doesn't need anything cleansed.

But if you just had access to all the skills you wouldn't need to stop and swap. What is the point of making us pick? Now I need to make a macro for the start of every dungeon that casts protect and then swaps it out for something that's useful in combat. WHY? It can only lead to me being more annoyed by early pulls. There is no positive side.
