I know what you mean. My nephew is ranked #2 nationally in pickleball men's doubles. He plays on a whole other level.
The shorter distances and slower whiffle ball make this a safer game for seniors than tennis. Injuries are just showing up on a national level because of the extremely high popularity. It's doing more good than harm. Leave pickleball alone.
I have to say pickleball is pretty much a dud in my blue state metro area. The local park district converted one of their tennis courts into 2 pickleball courts. I drive by or walk by the court on occasion and nobody is playing tennis or pickleball.
