What if your team wins and everyone on either team has low damage based on average in that mmr. What if getting 10 camps was what was necessary to win that game? What aspect helped him get the 10 camps? Did he have time because his team had a lead and he didn’t have to worry about xp as much? There are tons of other variables to consider there and about half of them are tied into how well off you are doing in the game which is tied to a shared experience pool.
