it would not matter how many squads want in, why cant they all get in at start? the more the better, if you are there at the start with your 6 guys then your in. turn friendly fire on make every one green and go for it.
two rules
10 K alt cap
no vulching
the only way to increase the limit of 5 squadrons would be to fly it like KOTH where everyone departs the centre field, flies away and then turns back in. I think this would be total anarchy trying to shepherd a possible 40-50 people to all turn around and re-enter the danger zone.
The second option would be to (as suns suggests) have a different shape with the possibility of even more fields. With the current activity levels of SDL I went with 5 as the maximum. This will also not cause any UFO moments with a high number of pilots all within the same area.
The map does have a 4 and 3 field bowl, if extra squads do show and there is spare CM staff to host the other bowls I don't see why they can't have a go too. Say a total of 7 squads show 5 battle it out and the other two can have more traditional SDL 1vs1's. Registration is done on a first come, first served basis an hour before the event.
there is a 10k cloud layer with max updraft. The initial entry into the danger zone will be capped at 5k. The bases are all 4k high with the rest of the bowl at sea level. This means that if you dive off your field you can try and drag people down. A similar effect to the DA furball lake.
squads are not allowed to cross other teams radar circles, this represents the no fly zones.
If we find the 15 minute timer is too short for the distances involved then we can up it to 20mins whatever works best. I will start the 15 minutes when the fight is on is called and it takes roughly 2 and a half minutes to fly from wheels up to the middle at 5k level. There has to be some sort of time constraint to push people into engaging. If you had a 45 minute window I feel it would fizzle out after 20 minutes or so. By resetting and going again you refresh the intensity.
