When I first heard about the stormcall shout I figured it'd just have a little patch of rain for about 10 seconds, and a big lightning strike, but from what we saw it completely alters the weather for the rest of the battle. This is a really awesome implementation and makes it worthwhile to learn this shout. So what others would you like to see that effect the game world around you?

I'd like a tornada shout, which forms a tornado around the player, keeping the dragon inside or out. If the dragon is outside the tornado when formed, it gives you a brief moment of respite to heal yourself and change equipment, or if you box the dragon it cannot fly away, but you can't escape either.

I know there's not a lot you can do with the environment, but all ideas are welcome
