Just increase the puffy ack over the strats... Eliminates the need to do anything additional with the C47.
I understand the frustration in resupplying strats and HQ. But I don't think adjusting the C47 to formations would be the answer IMHO. I like where you are going with it though.
Maybe more batteries at least 25 miles out...
Make it tougher for 1 lanc to drop a HQ.
I am all about strat runs. in fact, my squad gets together in B29s and make strat runs a lot. It is fun, and we risk bomber perkies doing it so others do have the chance to rack up points defending.
But I still get hung up on the single set of lancs able to drop a HQ.
