In FSO, bomber calibration is always a touchy subject. It shouldn't be, but it is. With a new game, and new maps, and base layouts, calibration should be MA standard.
We also have issue where bases are obstructed at times with clouds, and if you have a lower end rig, I hear you may have a tough time actually seeing the target to get bombs out in time.
It's a tough gig when you run into everything the other side has to throw at ya. Given the setup, and how the Axis ran their ops, they had every fighter squad available for defense of targets when the Allies hit.
Hopefully you get fighters in the next 2 frames, then maybe you will not feel like a stocking stuffer.
