I had a full Blizzard build drop the second day of season( magefist, snowclash, vipermage, and a blizzard orb) and didn’t even make a cold sorc for it, but I Tried it a bit yesterday and felt really powerful even though I didn’t spec into it
but had that funny moment out of it at least 
i hate blizzard the company. i’m like blizzard’s crazy ex girlfriend. We broke up, but im still here very angry at them, and wiish things would go back to the way it was when we first met.
if you dont like blizzard, try Frost Nova (w/ sunder charm). You basically cast blizzard on a crowd once, then teleport in and spam frost nova. or dont use blizzard at all, Frost Nova is pretty sweet.
I never liked Blizzard myself since Blizzard North and their “Works as Intended” attitude. But you play the game and not company.
