I think there needs to be some sort of balancing across the elemental aoe dots and single target dots overall damage vs time and sp.
Right now fully specced for ice.. ice storm is ALMOST as good as a completely unspecced firewall from the same toon.
The only thing that pulls ice ahead from fully unspecced firewall is the elemental weakness thing. Which takes quite some time to stack up where its useful.
It's pretty stupid i get a better return as an ice savant by spamming firewall.
Same goes for burning blood. It's a MUCH better single target dot than either the cold or electric. Just on the cooldown timer alone. I can spam burning blood twice as fast as either the cold or electric. And get better damage out of it as well.
You can spec for cold or electric. But you'll STILL be getting a better return out of your acid spells and fire spells than you will from your uber specced cold or electric stuff. its... messed up.
