a 1900+ player should never be matched with a bunch of 1500s. It's like taking a lion and dropping it in a pool full of pirhanas, its a sad thing to see.
I totally agree and I said a few times on this forum that the matchmaking now is far from ideal (to say the least). And other players also said that. I believe the developers will fix it.
Now imagine that they fixed it and 1900+ players will play with others from 1800+ to 2000+ only. Will you still say "this game is dead"?

I would argue that even people deciding to attack the higher rated player is part of it and is included in your edge.
But I can see how that might make it so that your goal of having fun is compromised in a given individual game when your rating is very high.
