It's not just combat and projectile weapons that suffer due to increased agility, immersion does as well. Flying my ship you would have no idea that it could rival Warhammer 40K Dreadnought for size, you would just think, 'hmm, this heavy fighter could do with a bit more strafe speed'.
It also rail roads you into weapon choices, the slower projectiles being automatically rejected leaving only a few guns viable to use.
