agreed, i'd love a change like that.
unholy is far from crappy, but i think a lot of people call it that because overall it's sub-par to frost. which is sad as unholy is my favorite spec, i just never play it anymore, in fact i'm now transitioning over to dw-frost as i have 1 heroic sha and 1-heroic elegon weapons and overall with all the cleave fights dw is best dk spec. so i welcome this fix in 5.2, but i don't think it will be near enough to bring it up to par with other melee classes or with frost.
