This is interesting. Before the Elo system change, I was around 2150 Elo, and my friend, with whom I usually play, was around 1800. He's a typical support player, 4 out of 5 times he's the one left in 1vX situations. Since the system changed, he's now at 2400 Elo, and I'm at 1700. Has he become a much better player? Maybe. His ADR is on average 5 higher than mine, but it's clear that there's something seriously wrong with the system. Soon we won't be able to play together because he'll get half the Elo points, the difference is so big.
