I've asked a couple people but can't seem to get the correct answer, I know FDK's provide improved Icy talons for the haste and BDK's provide Abomination's Might for the extra AP. But what do Unholy's provide? I know their AoE dps is pretty significant and most 25 runs ask for at least 1 - 2 DK's one of which being an Unholy. So my question is what do they provide as far raid buffs go?
