Keassa,
In truth, the EW/MW concept would be sound, if not for one thing...
It has to have a more complete planeset.
With some accompanied GV's(Pz III, Matilda, Crusader, ?)
EW ack (MG's, or different guns on the airfield, for example)
Take an expanded planeset, Only enable it in EW/MW, and see what happens.
