Hey, bumping this thread because I think there's something of merit in the OP.
When engaging ground threats, the vast majority of the fire is going to hit the belly of the aircraft, right?
In an air engagement, and I'm basing this off of REAL engagements because I don't dogfight in MWLL, but the majority of dogfighting kills occur against the TOP of an aircraft (typically in turns).
So why not just make the TOP of all ASFs extra-vulnerable, or make most of it 'engine' hitbox?
I do agree though that the hitboxes should be fixed. It seems like 90% of the fapping model is 'Body' no matter where you hit it.
