Put it this way.
When Beast gazed into the Black Vortex, and got a massive amp to his stats....what was the biggest improvement he had?
Was he suddenly Hulk-strong?
Spiderman-agile?
Feral Wolverine level?
No. It was his mind that was amped maasively. THAT'S his defining trait, and his main strength. Sure, he can throw down occasionally - but his niche in the X-men is for his mind. And thus, the majority of his showings will showcase this. For everything else, they have Wolverine.
