I absolutely agree that these games shouldn't happen, but consider this:
It's perfectly fine to not want to group up, but if you did group up, the outcome would have been the same. The top pvp guilds play a ton, and have become really really good..
True so what is the answer, matchmaking will not happen because it has the same effect as splitting queues. i.e. it will result in poor queue times.
You have to ask why do top pvp guilds (or premades) take part in roflstomping?
They do it because it is profitable! If it was no longer profitable then they wouldnt do it surely???
