Larian could allow teleport or featherfall to work on allies and items but not enemies. Also that would be consistent with Gawin task.
Being able to teleport enemies was OP in DOS1 at level 1. In DOS2 you get it around level 3 and fortify negates it so it isn't that OP. Also since AI improvement the enemies are constantly running right past my fighters and up to my mage/ranger, WHEN IT ISN'T EVEN THEIR TURN.
Literally on a bunch of fights the enemy moves on their turn, and after their turn is over the just keep moving. Until Larian fixes that bug, Teleport is an essential skill to throw them back. So wouldn't want teleport removed or gimped, but maybe get at higher level and get featherfall early on or on the gloves.
Hopefully people can chill out a little bit. Please remember a lot of this stuff is a matter of personal preference, not about being 'right'.
