Just been in a game where 3 tanks suicide due to MM

Dakiras: It's mentality. The wrong mentality, though. Even playing a light with scout MM, there should be no cause to give up... but I guess some people do. A lot of people like to focus on negativity and before they even try to effect (this is the right effect) victory they give up and go back to garage ASAP.   Just report these people in-game. If you run out, know that there will more than likely be others already reporting them in-game. If everyone has the same view of these types of players then there should be numerous reports against them.
