Just had a Bounty match where this person stood in the corner of our spawn, shooting at the walls, and letting himself die constantly, making this essentially a 4v2.

We need a report function, for people who throw/troll/AFK the game on purpose to make their team "lose for the lulz", penalise them from matchmaking, or if they commit to such acts constantly, pit them only against other players who do the same, and they can enjoy 3v3 AFK match.

A report function followed by an automated system which can determine the amount of damage/kills/assists one player does. If its zero or close to zero, no need for human intervention, automatically penalised. If its a low amount, perhaps a support team to check on the replay manually.
