so i've been playing an unholy pvp dk on icecrown and i wanted to get into pve.
Now i know frost does higher dps than unholy (exept AoE) but my question is how big is the difference.
from one point of view it would take me less time to gear unholy pve because i have some of the bis items already(like the weapon, trinkets,rings,neck,cloak).
but on the other hand unholy might be too weak to be any good.
now if the difference isnt huge i'd rather play unholy but if it is a big difference ill just starting gearing up frost from scratch.
so basically my question is if unholy is valid in pve and how big is the difference between unholy and frost.
