I agree Desire and this happened during the last round. Guy went straight to a glitched spot, got stuck, and didn't contribute from wave 1 on. Just stayed in some barrels or whatever stuck.
Had everyone died there is no way he could've helped win. Everyone would've been left to watch the virgin die. Just a tough call because he's a dtv veteran and should've known better.
I think desire might mean kick him just before the last wave, not round. Otherwise you're letting him get a bunch of free xp, all while making it harder for everyone else, round after round. If on wave 1 of the last round (or any other round) he runs and afks, then as desire suggested, wait until things are wrapping up round 3 to kick him, that way he has some hope of returning and contributing to the team.
Also, as far as I know prof changed dtv so that the virgin can die, and if she does you don't lose, but you lose a significant amount of xp from the end-of-round rewards. In other words, if someone is afk in a spot where the bots can't reach them, the round will never end.
