I use it practically every time that there is more than 3 enemies. It is my favorite shout.

Kinda understand what you mean. Especially when I'm playing my pure mage and I have other similar powers as well. I think the recovery time after a shout also makes me "forget" them for a while, too. Pretty much the only shout I use even namely frequently would be the good ol' trademark Unrelenting Fus-Ro-Dah that always comes to my mind when there's an animal or a hostile animal/NPC next to a drop with a long way down...

On topic, I think I used Storm Call yesterday the first time without saving/loading. I only recently got it legitimately maxed with a character for the first time, so I decided to try it out to see if it could clear the whole Karthspire Camp off Forsworn. It couldn't. It was still very lame in terms of its range.

I guess whomever it hits, it hits pretty hard. Still, the lightnings didn't mainly even kill those high-level Forsworn closest to me without my Destruction assistance, so I was overally kinda disappointed of this "The Most Epic of All Shouts'" full potential. Also the recovery time is so long I won't be using it for a while. Maybe I'll test it again on a smaller scale sometime, but will not use it as a weapon. My Destruction + Conjuration + Illusion magic is muuuch tougher than that storm. Visually the shout is pretty cool though, but that's not enough reasons for me to begin to use it.

That made me laugh. Very typical thing to happen though. I've only used it once when I first unlocked it just to see what it would do but no one was around.

I just used it with my mage character as he attacked the Lost Valley Redoubt (with the leap). I have no companions but quickly summoned a storm atronach and began throwing around chain lightnings and thunderbolts as the sky tore them apart. Suffice to say there was a very pretty lightshow, and lots of ash piles all over the place
