Add escort XP. If you in a fighter plane stay with a bomber within 1km distance you will get 20xp per bomber achieved kill.
This way there will be atleast some point to protect bombers like the JU188, since for each kill you can get 20xp. And bomb yourself if you have bombs, just stick close to the bomber to get the escort XP
You are also pretty much not doing anything while “escorting”
You could be attacking points and killing the enemy as infantry, at worst you could be wasting a slot for a much better plane
