CM or cold synergy? I have a level 71 sorc who has maxed meteor, fireball and blizz, 1 in FM and 1 in CM - going for a blizzballer btw. But i notice the extra points in glacial spike dont make a big difference. Should I pump glacial spike or cm to boost blizzard? My hunch is CM but not sure. Am on hell but doing NM baal runs to get tals ammy and belt - have other tal gear already.
