Warlocks can do that, what sunsinger should have been

Anytime I think of a paladin, I think of cecil from final fantasy. He's the paladin of paladins in my eyes. He deals massive damage, and also has protect abilities. So maybe some type of class that deals damage, and while it's dealing damage output, there's certain ability options that allow certain things as it happens. Such as, the more damage you deal, your team mates gain health back, almost like a venom drain. Or perhaps they gain shields and they last longer with the more enemies you kill. I dunno. I just want something green. Lol
