I've always wanted to see Telekinesis as a weapon, think there is any chance of doing this?

And as for pure speculation, what would your most dastardly scheme exploiting such a fun mechanic if it ever came to be?

I think I would throw rats at civilians (precious rats!) just to see what they did.

Telekinesis went under Mysticism in Morrowind and Oblivion. As far as I know they removed Mysticism in Skyrim. Do not despair yet, though! It may be under some other school of magic.

How would I like to see mysticism act as a weapon? Probably like a gravity pull where you can pull your enemies near you (archers and mages?) or reverse that... rapidly push them against away, doing damage (equal to fall damage, depending on how far the enemy flies). It would also be nice to push-shoot arrows, darts and other pointy objects at enemies.

I imagine the gravity push would look like something like this: http://www.youtube.com/watch?v=GmBcv2kC17M

I wouldn't mind seeing it like the Gravity Gun from Half-Life 2; to lift objects (maybe people if you're powerful enough) and throw them backwards.

OT: I always thought that a conjurer could summon a rat inside someone's stomach, or inside their skull for an instant kill.

I would like to see puzzles in some dungeons especially main quest related dungeons in which magic or other skills would be needed. It would add to the gameplay a great deal in my opinion.

Telekinesis in Skyrim is supposed to be more like it was in BioShock.

This.
