As a casual who didn't start playing shooter games until late, if it wasn't for SBMM I wouldn't be playing them at all.
The real evil is engagement based matchmaking. I don't want to beat players even newer than me every time I haven't won in 20 games, and I certainly don't want to be steamrolled by players who have been playing their whole lives when the same happens to them.
I used to really love this game. It has so much potential to be more than a battle royale, but it took like 4 years to get a permanent non BR gamemode. Battle passes only work if your players don't get burnt out... And don't get me started on collection events 2: electric boogaloo, this time with more gambling!
