Please forgive me, I don't mean to come across as rude in my replies but I feel you're looking at this from the wrong perspective. Many of the skills you suggest don't belong on a tanks bar at all (from my perspective). Take cure II, paladin doesn't have the mind to make it as viable as you think, instead you are taking the major healing away from another job that should be handling it in the first place. Protect is something that a paladin shouldn't have either, again, that kind of mitigation is the healers role. Holy? Why would you put the iconic whm skill that has BEEN a whm skill since FF1 on a paladin? Raise, again, while I can see the value of having that, your cast times would be ridiculous as you can't pair it with swiftcast and you will lose hate to do that raise. Nor does it generate enough hate to be a good thing. Cover should be easier to use, I agree with that. As for riot blade? I feel you there, but they use it for a different reason, it just happens to have a similar name is all.
Again, I'm sorry if these come across as rude, I just wanted to add my thoughts on it.
