I have one use for the rotate-thingie:
If a character for example throws something (and it isn't a dart or something similar) it'll probably rotate while flying. It will actually look kind of stiff if it DOESN'T rotate! Of course you can do an animationloop for it but it'd be much easier to just rotate one sprite.
Another use for it:
If you have some kind of pendulum which moves back and forward the rotate-command would also be useful. The pendulum doesn't necessarily have to be a grandfatherclock-pendulum but could just as well be something hanging from a thread, like a human or something. A rotate command would actually make it possible to have the human speak or do some other animation while dangling back and forward. Which would be quite hard to do with animations.
