If you stand in the lightning for two burst, you deserve to die. If the lightning finishes you after already taking ballistic damage, then it's the same as any other grenade. Titans have the lowest neutral game out of all classes and I believe this is offset by them having the best grenades for all of their subclasses. And when I say best I don't mean that no other class has a better grenade, but Titans have a grenade for any occasion.
