My understanding is the campaign would not be a league event, but like what we had last year. I took the squadron support would be to mean stat's would be maintained for participating squadrons. I'd prefer that squadrons be free to play whatever sized scenarios they like. I don't think larger squadrons have any problems with fielding smaller flights to face off vs smaller ones.
Personally, I'd prefer to see a limit of 1x2 as the smallest allowed game for campaign purposes, as last year, I saw a lot of 1x1s posted where experienced pilots feasted on less experienced ones. However, I realize different folks have different tastes... so, hey, to each their own
