This doesn't need to be explained massively in depth, as anyone who enjoys their fighters will understand. But the new plane mechanics are hideous. Bombers and attack planes haven't necessarily changed a huge amount, but fighters just feel awful and aren't half as fun as they used to be.
I'm failing to see how anything they've done could benefit 'the experienced pilot', when they now handle like a ferry.
Whenever you try to gently move the nose, the plane bounces around like it's strapped to a bungee cord (like how tanks do if you're trying to aim whilst on an uneven surface) and pulling out of dives is near enough impossible without colliding with the ground. Everything about the manoeuvrability feels off.
It's incredibly frustrating when out of the long list of problems that this game has and of the things that needed attention and fixing, they chose to patch the planes.
