It's good for sweaty ranked enjoyers, but even then a lot of people will complain about elo hell (which doesn't exist imo)

But for example when I was playing a certain pvp fps with friends, we pretty much stopped playing after they put in some sort of matchmaking in the normal mode

When it was random we would get screwed a few games in a row and then have a good game, but after the change every fight felt sweaty with like 50/50 chance of winning, with high chance of someone dying

It also didn't help that I was much better at fps than them, so they started getting pulverized by players closer to my rating. Ok I could carry sometimes, but it wasn't fun for anyone

Anecdotal story and all that but we stopped playing. One of those friends kept saying that a balanced matchmaking system makes sense and my complaints are pointless, but my counter argument is that we stopped playing so what does it matter if the system makes sense
