Given that one of the reasons we do so little actual fighting in cutscenes is for them having to account for you being every available job and then having to go back and animate any new ones added, I've always hoped we'd get some generic WoL powers we could use in the story that all of us would have access to independent of our job, like the barrier we use to protect people from tempering and the weapons of light we sparsely use.
Hopefully if we do use the crystal, that's one of the things it leads to, would love to see us a little more animated during combat cutscenes.
