Holy Freeze Paladin?

I hear they are a lot of fun, and I can see why the would be, but how are they performance wise? With so many other sources of cold from other players it seems like it would mostly be redundant. How do they compete damage wise, and can it really be worth not slotting a group buff?

I’m going holy freeze zealer day one on hardcore and teaming with my buddy that’s a necro. Slapping a slow on all the monsters around you is pretty helpful. :slight_smile:
