I do find uses for Shake It Off, but these are normally "Oops, I screwed up and stood in a telegraph" sort of things, and in any content that has a healer, I normally see an Esuna half a second afterwards, so it's really not that good. The only case where I've been actually glad to have it was the other day when participating in a hunt with only a Chocobo to help me. Used that to remove any poison or blind effect I got hit with.

Still not a good skill in the grand scheme of things. Did the Dev team think that we didn't deserve anything good?
