I can't stress the amount of times that at least 2 players on a given team fit the criteria of

1) foreign griefer (item destroyer, incessant flaming, all around bad play, you know the deal

2) account buyer (high rank, hero's with 0 Winstreak being top score meaning account was bought) or optionally, 15 streak on a hero they don't play.

3) is absolute keen on playing some random bullshit that they don't know how to play that they've seen on YouTube in ranked (kotl mid or some other weird thing that doesn't work in solo queue)

Like the fact that I can basically look at accounts pretty game and accurately guess which team is going to win means this is fucking ridiculous. There is absolutely no measures in place to detect people who are too high rank. People who are too LOW rank have mmr acceleration, but people who are too HIGH rank do not receive deceleration.

The higher up the ladder you go, the extreme variability of player skill increases, full stop. I started in crusader and I never found people who I thought "this guy shouldn't be crusader" outside of the occasional smurf. I'm now mid divine and it's almost a coin flip of whether they are an actual player or not.
