Meeting all of the critera @
Faroth asked for is impossible. Unfortunately Protect can only ever be a bland damage reduction skill - it owes too much to previous FF titles to be anything other else. For it to be impactful it'll need to be
really powerful and therefore needs to be on a longer cooldown to keep it inline.
I would much rather see it taken the other way instead. Becoming a very obvious, very powerful skill makes it a tool players feel comfortable with as well as one that has a noticable effect on the rest of the group.
