Only one I can think of, Cloudkill. All other are effected AFAIK.
I am not sure that I would completely agree that WoF is overpowered. Maybe slightly, but not dramatically. There are *significant* issues with many if not most of the arcane damage spells in the game, making WoF just about the the only effective weapon casters have for purposes of damage. Cloudkill is the only other arcane spell that even comes close to be effective.
My opinion is the real void for casters is DoT spells. There are only 2 in game. 1) Melf's is mediocre, at best, and 2) Burning Blood, is pathetic. If anything is ever done to nerf WoF, DoT spells *need* to be addressed to compensate.
A couple of restrictions on persistent AoE spells that might be reasonable would be to take HP damage from only 1 at a time, and to "improve" the over-lay avoidance, so as to make it much harder to blanket an area with walls. Do something like make it so a caster can only maintain 1 WoF at a time or some such.
As has been pointed out, the issue with all AoE isn't the damage that it deals, but the failure of AI to retreat from it. However, without WoF, a caster falls significantly behind every other class in the game, except, maybe, bard.
