Ice Nova's knockback on hit is a real pain in the ass for cold sorc

Nice clump of mobs, frostbolt towards them, ice nova the frostbolt, big donut of mobs now that cant be aoe'd :(

Yeah it's honestly a pretty horrible spell. I dumped it as soon as I got frost wall, and probably could have done without it before. Early game I guess it's pretty important for not getting swarmed, but the knockback shouldn't be applied to the frostbolt explosions.
