Thanks to Boojum, everyone teleporting together at their spawn no longer necessarily appears in the same spot (1 in 6 chance now). The reinforcement teleporter still teleports everyone to the same spot. Other changes as in the revision log.
At this point I'm looking for opinions on the 6 teleporter exits for each team and whether or not they are in good spots. Additionally, I'm considering making the arena area larger, and would like to hear your opinions on that subject.
As always, any other suggestions are greatly appreciated, particularly those made in this thread.
