Cold Spells feel terrible....

I pretty much play exclusively casters most of the time. And the new poe 2 cold spells while....sure they're big and flashy. They scale horribly. Especially Ice Nova. End up slapping an white enemy 20 times just to kill it even with damage supports, full cold damage on tree and spell damage, and well over 100% increase from items and +4 on gems they still feel bad.

I enjoy the cold snap method of triggering a payoff...but The set up takes so long to achieve I coulda just played with a different element. And it doesn't make sense like...is a damage switch off or something on cold spells? Is call of the brotherhood lightning or bracers fire the only way we're expected to deal cold spell damage? What gives?
