Well a lot of games are that way, and I had it happen it was 15 to 14 we were about to win but we all died and noticed a afk person and the other team won because they defused the bomb I was triggerd.
If someone has to go AFK for a round it's no biggy but the guys who are gone for like more then that really suck. Or the guys who join to try to derank by going AFK piss me off. I rather have a stupid bot on my team then one them, and by bot I mean built in the game not a cheater.
