All true.
What do you think would happen if most RAF bomber missions were removed? Do you think they are a distraction for the 109s from the job of escorting and sweeping?
It would be interesting to try one map where the 109s have nothing to do except escort and sweep. No RAF bombers and massive AAA to stop vulching.
Of course that might empty the server of Blues, perhaps our best bet is the occasional SOWC for that 'BoB' feel.
