would be nice to get a majority surrender (instead of unanimous) This would solve alot of these issues with holdouts and having to quit.
In fact it is not unanimous. If someone decides not to vote, other players can choose without his vote. There is a veto though, at least i'm sure of it that in 2v2 and 3v3 one guy disagreeing is enough. In 4v4 i think 3:1 means still surrender, so there is no veto, but I'm not sure of it.
