In my playthrough, in the late game, I put 4 points into INT on my Warrior specifically to wear some mage armor to buff up the weaker magical armor, and I did the opposite on my mages, so that hasn't changed much.
Telekinesis is largely in this game because it was thought to be a neat thing to have in DOS 1. It's never actually been terribly useful for gameplay, except maybe stealing different things. It could have been better if they'd added a skill to let you use it for more interactions.
