How about my idea... make it a bit more iffy against lower level spells and give whiplash effects even a small amount of damage d4+spell level? of a type related to the spell countered. (if any) or a type opposite.
And conversely when I fail to counter it i might take a small amount of damage of the opposite type maybe?
I actually like that much better as a subclass feature for a sorcerer or wizard than I do for the whole game.
