I'm sorry, I can't imagine ANY universe where "I can kill you with my mind." is seen as a "trash" skill. At best you're a superhero on par with Martian Manhunter, Jean Grey, or Superboy (who literally uses tactile telekinesis to replicate being as strong as Superman) and at worst you're a deadly opponent able to make anything around you a weapon. Take the force in Star Wars which operates similarly, even a padawan on the battlefield with the force is DEADLY. You can deflect some attacks, improve your own abilities (I'm sure any telekinesis can be used to lighten your own body and replicate a force jump), and even simply knocking someone off balance is fatal in a combat situation.
Yet we're going with that it's not only bad, but so bad you need 2000 years to try with it. **** off.
