Watching the old WWII movies about bombers I came to a solution for the diving bombers problem.
Pilots put their planes on autopilot, bombadiers took control of the plane. Made last minute adjustments, lined up the plane, the sight and let fly.
All Hitech has to do to fix the dive bombing hvy bombers problem. Is to tie bomb drop to autopilot. If the plane hasn't been in level autopilot for 20 seconds either the bombs don't drop. Or they drop 2 miles to the right or left of the target.
Roughly its a matter of programing a single switch that checks autopilot status and time.
For those bombers that historically could dive bomb, that switch is disabled.
For any real bomber fan, it adds realism and immersion. And it brings some sanity back to the main.
Ohh and give us back the hard calibration routine also.
Last, to encourage bombers, give them 2 or 3 LARGE targets per country.. Put all the strat objects for an area in one clump. Add a bunch of nice big factorys. Make it worth while to set up a good approach, figure salvo, delay etc and lay a path. In short, carpet bomb the area the way they actually did.
Put a GV spawn in the middle of the area that can spawn osties to discourage jabo's.
