Because if you set the caps static all the time instead of dynamic, you will end up with numbers like
LWO 400/400
LWB 40/400
which is much worse.
Understood Lusche. but whats the sense in making the cap back to where its able to enter if you just stand there and try for a few times? It can go from my example above 240/250, a minute later go to 235/100, but if your really stubborn, give it a few and that cap will end up being 260/450. If the goal is to keep people from hording one arena and preventing crickets chirping in the other, than why not have each arena at a reasonable say 250 or whatever?
