As a bit of a family, a community, 71 Squadron RAF doesn't like to kick out folks that are less active. While we might have "3 wings" -- we are still moderate in the amount of real players at any given time that will fly together.
Personally, because of this experience with the comraderie of 71 Squadron, "multi wings" doesn't really affect me so much as "horde squads" -- those squads where they can't engage a single con, run screaming for the hills, and only try to sneak or suicide pork fields with a solid wave of 12 planes or so.
These squads, although smaller, are far more annoying (and, dare I say "lame") than any multi-wing squad with a more laissez faire style of flying.
