Choker of the Firelord.. for Healers?

What is it about intellect on a paladin that makes it as good as healing power? Because I know it doesn’t give them healing power.

Pretty sure intellect is the same as it is for any other class, unless you’re referring to the 10% more intellect they get. But that’s nothing. You’re talking a single point more of intellect.

Do paladins have no means of gaining mana Regen while casting?
