First of all, its quality not quantity. In Wanda's personal case and the larger marvel universe, reality wrapping powers has worked better in more sci fiction and mutation based world of marvel than their more magical based world. Never said Magic does not have any claim on it, but the claim is far stronger with telepaths and psychics.
I remember on the TV/film discussion forum when Wandavision was airing in January, some quickly thought and said Wanda was like the MCU version of Jean Grey and the only reason she is that way is because marvel is saving Jean Grey.
Can you imagine the ignorance that anyone will think Wanda was a watered down Jean Grey? When Wanda should be more powerful than Jean Grey without Jean been enhanced by the Phoenix force
However The only reason for this ignorance beyond those that have zero clue on marvel comics and movies is that one of the easiest ways Wanda's powers was always explained was that she was some kind of psychic and we know for a fact which marvel series dwell the deepest into psychic related issues, that would be X-Men, not Avengers.
Again please see the idea where I said Wanda's kind of characters story arcs needs more than explosions, typical comic fights and world ending universe threats that has nothing to do with how far the genre has gone with story telling of psychoanalysis that feels smaller but much deeper in story telling and depth. lolWanda had over 50 years with the Avengers. Literally thousands of comics. Evolution ran counter to everything her character was for most of her career
