Hey! So, it has occurred to me, that it could be sort of fun to have a possible respawn timer added into KoTH. That way, it is not instant respawn and they are back at the hill. I think it would add a little more severity to a rush in a KoTH game. Your life suddenly becomes just a tad more valuable.
The command could be:
ARENA SETUP <Arena> SPAWNTIME <0-90 seconds>
ARENA SETUP <Arena> SPAWNTIME ON|OFF
Edit: I actually think this should just go for KoTH. CvA is fine as is.
