Have default gravity for Runway, otherwise you can climb out of the map.
I didn't know that. I guess I will find a new map for rocket arena.
Cradle, if you're feeling suicidal. Or a map with wide open spaces indoors, like Stack (or Library), though you may not want to lower the gravity on that one since you will be headbutting the ceiling more often than it's considered comfortable.
Montly events = good idea. I hope people will get aware of these events. There's advertisement on Troy's server and now on these forums, but perhaps more advertisement is still needed. We should spread the word.
I have not picked an official start map. I was thinking Control or Egyptian.
