How about Square Enix adding a skill that is able to make use of a Paladin`s enormous damage income?
Something that would be very usefull in a pinch and that could help the entire party?

For example:
A skill with a 15sec duration, and that would take 10% of the total damage taken by the Paladin and equally distribute it as HP to the other party members.
Putting a long recast (3 minutes maybe?) would be enough to prevent over-usage.

It is a nice idea, no? I think it also fits with the "Paladin" theme, where he would get hurt to protect those around him.
Maybe add this as a Level 50 skill, with the need to complete a certain quest to get it would be interesting, no?
