A point to consider about the objectives. With the old 32 plane limit, and over 500 registered participants in FSO, there were numerous complaints about aircraft just suddenly appearing out of nowhere. To alleviate the old issue, it was best to have enough objectives so that only 30 or 40 players would be at any one of them.
With the current version of Aces High the number has increased to 64 players within 3,000 yards that will allow for more players to be in one area. However, this is new, and it's better to be cautious with the objectives in case there are performance issues with that many planes close together.
