Does anyone use Icecap?

Seems like a very lackluster talent that is never used. Bring back Necrotic Plague and put it in it's place.
8.1 doesn't look good for dks either, Frosts don't seem to be in a good spot at all.
Uh dks have potential.....I will be testing them on the PTR soon, but they don't seem all better from what I gathered.
