After careful consideration, I have decided to bring TPU back online, with some changes. No punitive actions will be taken at this time, although that is still a possibility if things don't calm down.
The team ratio on all TPU maps is now 3:1 instead of 2:1. Since I cannot force players to play co-operatively or to avoid disrupting each other, I have decided to adjust the server parameters, with the hope that this will make co-operative play necessary in order to win. At the very least, I hope that this change will force players to break out of their habits and find new ways to play, win, and have fun on TPU.
I will continue to monitor the situation on TPU and will make additional changes if necessary.
Meanwhile, I'd like to encourage all players, especially the admins, to be more respectful of each other. Don't assume another player is trying to disrupt your gameplay. Instead, try asking them politely to play in a way that allows everyone to enjoy themselves. They may not even realize what they are doing is disruptive. If another player asks you to adjust your gameplay, respect their wishes, get creative, and find a way to win the battle while allowing everyone to have fun.
Finally, take a moment to think about the soldiers in WWII who never saw combat. Some soldiers in the 101st airborne in Europe never saw any action, despite being dropped into Normandy and Holland, and being in Bastogne. I'm sure some of these guys felt cheated. I'm sure some of them wanted desperately to see action, and I'm sure they talked about it. But did they accuse the guys who saw action of stealing their fun? I doubt it. Some jobs in war are less heroic than others. Someone has to man the artillery. Someone has to transport vehicles. Someone has to guard lonely outposts. If your team wins, you win, regardless of the way it happened and how many kills you got.
