Mixtape:
I agree that there is more variety (regarding skill) in Mixtape, but there still 100% is matchmaking ratings in mixtape. My mixtape matches are typically (like 80% of the time) comprised of all 4k 20 bomb players. This is super easy to confirm because you can consistently assess your killers stats.
So please know that at any given time, you are being protected from the top players. If that’s not enough and you are committed to experiencing a “close match” every single game, then I would respectfully recommend you play single player games (where the difficulty is easily manipulated). To be fair, there are “blow outs” or ”shut outs” in casual AND professional activities/sports.
As for the new event:
Its a breath of fresh air and thankfully its not the only playable mode. If you want to avoid it, then duos and ranked is still available. They probably didn’t make it an entirely separate mode because they didn’t want to split the playerbase— which would impact queue times even more (I’m already waiting 3-5 minutes for a game).
