Ok now for the questions.
Victory points will be calculated for what we hold on the last day? Rather than for every time things change hands?
Yea IMO that's a make or break issue with this set up. I flew some the last time AvA was set up with the land grab set up and points were awarded for the new base captures only. So it led to milk runners bum rushing the bases on their squad nights trying to get as many bases as possible just for the points, but never trying to defend them.
IMHO the only way to stop the milk running for points vs playing a strategic fight is to make them hold the base for a certain amount of time. That means they can't just run a bunch of bombers across the map stealing base after base for points, then letting them get recaptured 5 mins later because they didn't defend what they captured.
That's why I ended up not flying in AvA anymore, there were some good nights of tough fights at the start of it, but then it started turning into milk run land grabs for the capture points. Once that happened I ended up going back to the MA's.
I think a simple required hold time for a captured base would help stop the points milk running and make each team fight for the objectives & defend them. JMHO.
