I was thinking that it would be great if Genetic Damage wasn't just radiation attack type for purposes of defenses. I know I've seen some creative swaps for other damage types. Imagine swapping hex or another magical effect for gene damage? Take that, Superman!
I think it would work to have, for instance, hex, panic and power null be swappable to gene damage, to give people some options. The restrictions (characters who are stunned can't be gene damaged, etc.) should probably remain the same, though...
