Workshop gives nice choices to tailor the game based on various preferences. If I were to add an extra feature, then it would be the ability to adjust aircraft numbers inside squads for both friendly and enemy sides.

So, you'd have the option to have empty skies with few lone wolf patrols. Then you can gradually increase the numbers towards late 1917 into 1918 (like dropdown boxes with number choices from one to eight).

This is different from "less air activity" which makes less airbases active, but still generates upto 6 planes in a squad.

It would be an option, so those that want constant action in every mission can still have it and those that want more realistic encounter rates can have it as well.

As I'm playing right now, I don't get a chance to become familiar with my squadmates. They are constantly being replaced because they die in missions. Apart from historical aces, I haven't had a single sqadmate survive more than 3 missions - and this is in early 1916, too!
