I guess this is my reasoning, first of all I don't want the guys who have to score the event to spend a week combing over the logs for every single time someone rearms at the wrong base. Granted I could/am usually wrong but I see this as a minor issue compared the event as a whole. As a bomber GL the rearms don't concern me as I have to RTB to replane anyway, but if it causes a great imbalance then I agree something might have to be done.
What worries me is every time we have nit-picky rules it almost always leads to arguments which can mar an event in the end.
Unless something happens I expect to be GLing the B25's in the event. While everyone is worrying about upgrading to G6s or Spit 9s, and where to rearm, I'm worried about how badly my squadron might get slaughtered during the event and how many pilots I might lose. I worry about how I as a GL can ensure the pilots under my command have a good time and don't leave out of frustration. I do want to win, but I want to have fun overall.
