I understand Lusches reasoning, but there are currently 4 people occupying the squadron rankings unfairly in this current list.
I was going to say that one of those is me. But you are looking at highest ranking squads, and I certainly don't qualify.
Back when my brother was flying with me, the two of us formed "The Oak Tree Air Force". He has had to drop out due to computer problems, and no telling when or if he will be able to come back. When it was the two of us, it was very handy to have a squad channel that I could use to teach him the game.
I think teaching scenarios like this would be a valid reason to keep the 2-person minimum rule.
