Ah, I see what you mean now with the aiming. Arguably this behavior is desirable since one would hope that your bullets would always fire towards the crosshair? I guess I tend to leave my crosshair as close to the boss as possible, if not directly on top of, so this hasn't been as issue for me. I see how this might trip you up in some scenarios, but I'm not sure if there's a better alternative. (A conclusion which you seem to already agree with, I think.)
