I think that a hurricane unit would be extremely useful, especially for fantasy mods. Not so much because it's needed to represent the natural disaster of a hurricane, but because in several fantasy worlds, storms can be controlled through sorcery. For example, in the world of Warhammer, the lizardmen once destroyed an armada from Cathay because their sorceries caused two hurricanes to strike the fleet. So, if a hurricane unit were made and given the hidden nationality trait, it would do nicely to represent such magical might.
Oh, and Ocedius, do you know how I could get that scorpion unit???
