The thing about night, dusk, dawn, etc., is it makes proper fighting very hard. Sure, you can see where the plane is because of the glow in the dark icons but, you can't discern its attitude or even tell whether you're looking at the top or the belly, it makes predicting moves next to impossible. In short it makes air to air combat incredibly difficult and un-fun. I do admit from a strictly eye-candy point of view it's quite neat though.
