I've played through Skyrim several times and I've noticed that the one lightning shout (STORM CALL) is almost useless as it is. While it is powerful and strikes multiple times over time, it is random and only works outdoors. Almost all the other shouts work everywhere and are easily managed.
That being said, there is both a FIRE BREATH shout and a FROST BREATH shout. Both of these do decent damage and possess the effects of their elementals (fire igniting enemies doing extra damage over time; frost doing stamina damage and slowing down the enemies). So, with that in mind, why not have a shock based breath shout rather than a shout that summons a lightning storm that strikes randomly? Easier to control in that you don't accidentally hit a friendly target and is useful against mages in the same way that frost breath is useful against warriors. It could be called STORM BREATH.
With Bethesda create a patch to change the shout? I doubt it. But what are your thoughts on this?
