@reconzero There actually isn't that wide of a skillgap. What we have is a "cheater gap". A large percentage of players in this game are cheating, from level 150 to MOST predator players being cheaters. The twitch apologists will come out and try to do some mental gymnastics about why their favorite streamer is the best in the game... but it doesn't logically make any sense.
The same few hundred people every. single. season. come out at the very top of the predator lists despite the fact that millions of people have played this game - with half a million on peak load play this game regularly. The bottom of the pred list shifts, but the same individuals are able to outclass just about everybody all of the time. That's not possible in a BR game which is inherently built upon "randomness" and which has so many disqualifying "issues" such as audiobugs and server problems.
The occam's razor explanation is that most players who win more than they lose at the far end of a deviation bell-curve are cheating. There's nothing to this game that makes it inherently different than any other shooting game. You can't say your aim in Apex is better than in MW2, because all the stuff you're going to say is different would be learnable within a couple hundred hours of gameplay (if you were actually that good). Moreover, Apex has built in junk that makes it nearly impossible to hit shots as well as some of these cheaters do, such as situations which you literally can't see anything on screen because there is smoke, some kind of flash animation going on, bushes, etc. the screen shakes violently whenever all sorts of stuff happens - grenades, getting shot, running, care package landing, smoke going off, traps, you name it - there are a huge myriad of reasons that it literally doesn't make sense how people make these shots.
More importantly, we have BUILT IN cheating with controller and console crossplay. Most "pros" have switched to controller or have teams built out with one or more controller players to cover for their aimbot. Yes, they are using controller AND aimbot. It's not possible for you to pick up a controller after not having any experience with it and within a hundred hours be top Pred again. Not possible. That would be like me being at expert racing level after just learning how to drive a stick shift in a car. Not possible. I might be rapidly progressing, but I cannot be an expert with such little time played. Yet, we have seen this on stream a few times with notable high level players.
I do agree with your assessment about bad matchmaking, and the rest of what you say about smurfing, and especially allowing solo queueing in a team game without offering a solo-only mode. meaning a mode which is built strictly of three-person teams only solo-queuers.
