he balances the game when there are only noobs on both sides, just to have a playable game. He doesn't do it for others, only for himself. When the other team is stronger (or just a hard game) he goes to the spectators and waits for the better team.
as u can see here:
he was red, he switched to blue and then he saw that he was going to lose and went to the spectators
in this game he was kicked because he winjoined
Yeap, he's a great guy, so concerned about balancing games, thanks a lot Bobi <3
