I don't see why everyone should want a remake. If you're playing a 4v5 since pistol then it should be an automatic remake if someone wants it. I had a game where a player refused to remake and we were stuck playing 4v5 the entire game. Why...

I get confused when to use the ult, but I usually use it when there are 4 or 3 players left on the enemy team. But I'd like to hear your opinions on it.
