If a surrender is a 3 yes votes, should the 2 no votes be ignored?
People are tired of playing a game and then two people constantly decline. Majority already doesn't want to play and this makes games much faster.
When the enemy has all towers up, but you only have your nexus. Two people decide to vote no. How much time will be wasted? What if the game is so bad and toxic it's a waste?
Essentially, the point I'm getting at is if 60% of the team wants to go - let them go. Nobody likes wasting time.
