Ok your an idiot because you can't do hell ballruns with blizzard k?
there is always immune to cold people such as dark lords and most the time the minions of baal have are immune to cold. a sorc usally can't do a baal run by her self. Even pindle hell is immune to cold quite often. The whole reason i made my leet blizzard sorc was for pindle bot but 2/3 of the time he is immune to cold...
