If they are so bad they can only manage 800 dmg, they should be in matches with other sub bronze players. Or they are just throwing on purpose to do that little.
Since s3 I’ve had these players in my qp games too. Everyone in the lobby on both teams will be like 2-4 elims per life, and then there is 1 person at 0.5. It’s clear as day they don’t belong in the match at all, but whatever they changes in s3 made it happen often.
