actually players can start getting superstar abilities as early as 60ovr...it's not just for the elites...again...your game, do what you want but I'd strongly advise you to research it before you tinker with it. Check out Geodude's description of Superstar abilities too:

P.S.
I'm nowhere near ready to concede that the "AI is clearly bugged out for superstar QBs"...I have not seen that. I've seen where poor pressure/coverage/play calling has made subpar QBs look great....but that happens in real life. And I've seen guys like Tom Brady go on a freaking tear and make my defense look helpless....also happens in real life. Maybe my 24+ games using armor and swords sliders (15min quarters) isn't a large enough sample size but I'm just not having the same issue you guys are.
