Why no non-lethal lightning? Isn't that pretty much just a taser? I mean, it's not like Clover's lightning is comparable in watts/voltage to a real bolt of lightning anyway.
A taser does stun damage. An AP of the power doing stun damage is completely understandable, but the +6 lightning is more powerful than any of the lethal guns being shot by the bad guys (at least until they crank em up a notch, anyway) and could certainly kill someone with low toughness and bad luck.
You could flip back and forth with the stun AP (that would be later on), or even just not going full power. A +3 attack I'd let be nonlethal.
