I love telepathy and telekinesis as powers but it's true that Marvel has let them run amok and are now super OP. Telepaths should largely be specialized in the use of their abilities, imo. The only mutation I "hate" is Shark Girl but that's because Aaron's students seemed like jokes to me. I also never understood was Risque's powers were supposed to be doing. Reality warping is getting a bad rap in this thread but it's always been a cool powerset to me.
“Strength is the lot of but a few privileged men; but austere perseverance, harsh and continuous, may be employed by the smallest of us and rarely fails of its purpose, for its silent power grows irresistibly greater with time.” Goethe
To be fair about the Telepathy hate mutants were created to be spies to take over different planets and there are not many powers that are better at doing that then telepathy
Telepathy is a weird one because non-mutants can just sort of 'learn' it. It's a standard feature of learning magic, as sorcerers and magicians learn telepathy as part of the 'trained powers' they have. Various human 'sensitives' work for SHIELD and even the Hand/Mandarin (during Psylocke's mind-swap with Kwannon). Alien training granted Bob the Uranian, Mantis and Moondragon telepathic gifts, despite them not being mutants. And Jean Grey herself wasn't a telepath, originally, but learned it from Xavier, her mutant power being telekinesis.
And, it seems, every mutant telepath can learn any trick any other mutant telepath knows, as easily as they can share / teach various skills and languages, probably because of Xavier handing out these tricks like candy to Jean, Betsy, etc.
Even when telepaths are shown with limits, like Emma, back in the day, needing a machine to swap her mind with Storm's, they tend to outgrow them, as she later swaps into Iceman's body without a machine, just using her own power, indicating that she's 'learned that skill' over time. (Well, out of story, indicating the writer didn't do the research, but, whatev.)
While there certainly is a measure of 'slip' involved with psionic abilities and I agree with your general premise, Emma's body switch with Bobby was not intentional on her part, nor solely due to her own powers. There was some kind of Shi'Ar power surge in the mansion while Bobby was attending to her comatose body and that was the trigger that caused the switch, not her own abilities.
Let the flames destroy all but that which is pure and true!
The fact that some humans can learn telepathy is kind of cool for me. I guess baseline humans in the MU have some latent psionic talents by themselves and maybe that's why telepathy is such a common mutation among humans compared to say eye-beams.
I'd like to see a human telepaths vs mutant telepaths battle in a future confrontation. Emma was much more powerful than the Purple Children in the latest Jessica Jones, and Jean was able to create blocks to keep Purple Man out if I'm not wrong (I know he's not a telepath per se, but he's been largely depicted as a telepathic being in the latest iterations with full-on mind possession and illusions and such).
The fact that Jean and Quentin are Omegas should suggest that human telepaths like Moondragon and Mantis cannot surpass them.
Yeah.. I also think with Jean having hopped into Emmas body it was already someting going on to allow her to move a little easier. One thing I always wondered was if Emma went into Bobby, did Bobby go into Emma's body.. Now that would have been interesting to see how he dealt with being in her body and having telepathy with his silly ass mind set.
I think telepathy, telekinesis and other mind based abilities such as energy and elemental manipulation always are a little ambiguous and abstract because to give that human minds are adaptable ( like the brain can re route itself if injured) and it shows that we have agency, the ability to do overcome barriers.
However, I do think there should be distinctive with the powers maybe like the Talents Series by author Anne McCaffrey. I liked how she framed mental abilities.
Oh her powers are localized inorganic matter implosion. It was later explained to include a measure of gravity manipulation that allowed her to hurl the imploded objects at people which then lead to her also using her power as typical blaster lol. She also was hinted at as having enhanced physical attributes. So to me she was localized gravity manipulator.
