For the purge maybe have it happen 48 hours prior or just for a full 24 hours and instead of having access to helis and tanks why don't we have the normal raiding tactics? In our last server it was so much fun trying to defend the base against raiders. Helis and tanks to me are not just that much fun at all. It's the raiding using the normal tactics that make it fun. Otherwise its just like what is the point in trying to defend against helis and tanks, there isnt any point.
