The only problem with Pyke is how safe his laning phase is
You simply can't punish him unless he really messes up. He is essentially immune to poke due to it doing half damage on him, and you can't all-in him becuase he dashes away while stunning you.
The only way you beat a Pyke is to counter his engage and lock him down, which means he can just zone you all lane without committing to anything. It's basically extremely hard to get a lead against him if he knows what he's doing, making him extremely safe, while he always had insane kill potential on you.
He strips you of your agency in lane, and that's just not fun
