Hmm, how about this: Gladiators are better for tanking and self-preservation, while Paladins are better for tanking while protecting others?

I do agree that PLD could use a few tweaks to improve some skills a bit, but maybe it's how we define the role of the PLD tank that needs to be reevaluated as well? Most (if not all) of the posts I'm seeing here is about using Holy Succor on yourself, when it looks like its purpose is to preserve others (while simultaneously benefiting yourself).
