Ok finally got to play it for the first time tonight, we had 13 in at one point and we were having a blast!!!
As has been said previously, the respawn is currently 10s, the general consensus seemed to be that shortening it to 5s would be good. The spawn protection also seemed to be a little long, which allowed you to sneak up on people to easily. Shortening that by 2-3s could be a good idea.
Other than that it is set up nicely, everyone seemed to enjoy it. It is currently set to 21 levels which is decent, and the two kills to move up and five to move down is set just about right I think. I wouldn't mind seeing maybe a sniper rifle/c4/smaw added, maybe other people can voice their opinions and we can see what is popular.
Other than that, thanks for setting it up!
