Agreed. Some of my favorite mutants, Dani Moonstar, Cypher, David Alleyne, Scanner, etc. have a power that's a tiny subset of what *every* telepath can do, right out of the box.
A telepath *should* be able to read minds, and project their thoughts, and there's no guarantee that their range will be significantly greater than a normal person can shout. (Certainly not worldwide!)
But slowly but surely, mutant telepaths have been able to;
read minds, project thoughts
astrally project (Scanner and Trance's entire mutant powers)
mind blast people
alter or erase memories (Dreamer's entire mutant power)
mind control people (Karma's entire mutant power)
implant hypnotic suggestions to go off later
swap minds with someone
alter someone sensory perceptions to make them see illusions, or not see the telepath or their allies (Moonstar or Mastermind's entire mutant power, with Dani having an even weaker subset of this!)
create psychic weapons (also something Dani has learned)
instantly learn any skills another person has (Prodigy's entire mutant power)
instantly teach any skills or languages to another person
translate any languages (Cypher's entire mutant power, although he one-ups the telepaths by also being able to translate written words or computer languages)
sense the presence of thinking minds in an area around themself
and I'm sure there's more!
It's actually kind of crazy. I'm waiting for someone to go a step past psychic weapons and start manifesting psychic *creatures* made of telepathic energy that cause real-feeling psychic wounds (just as Psylocke's psychic knife can make you feel like you've been stabbed by a real knife, only this telepath's 'focused totality' is a psychic tiger, T-rex, giant octopus or swarm of wasps!).
Telekinesis gets weird when it starts turning into a generic Green Lantern power, creating force fields and stuff. A telekinetic moves things. Creating force fields, not so much, although one could 'freeze' the air in front of them to make a shield, of sorts, or, more likely, grab something nearby and interpose it between themself and an attack, as a form of instant cover/shield.
But really, my biggest mutant power pet peeve is mutants
not using their power. Rogue and Ilyanna are major offenders here. Rogue leans pretty hard on the power she stole from Carol Danvers, and, IMO, has never really had to learn to control her actual mutant power, because she's a badass without even trying. If she had to work for a living, and use her *own* power, she'd probably have to adapt a very different fighting style, not being a mostly invulnerable flying powerhouse, moving acrobatically through the battlefield, until she can get close enough to tag people and take them out (if normal humans) and / or take their abilities (for superhumans). Ditto Ilyanna and her soul-sword/demon-queen of Limbo schtick. People like Blink and Nightcrawler manage to be pretty damn awesome and dynamic as all hell relying on the power that Ilyanna mostly uses to play team bus before and after the action.
Cable and Shatterstar are also guilty of this, but they get a partial pass because they were invented by a doof who forgot they were supposed to be *mutants* and their initial superpowers were 'guns' and 'swords' respectively, with a side of 'lots of pouches,' 'swole' and '90s attitude.' If you skip the speech balloons of their Liefield days, it's easy to think that Cable is a teleporter (since he bodyslides way more than he uses his actual mutant powers), and that Shatty has some sort of Toad-like leaping power, since he's always in a flying though the air in an awkward squatting posture, swords akimbo.
