You don't love having that one friend who just refuses to get better who cries about every death saying "this persons tryharding because they didn't stand there let me kill them". The reality is that you can use off-meta if you're good and the higher your skill level the better "bad" things can work because they often become unexpected. People just want pvp to feel like pve and their opponents to think like npcs. They like the "feeling" of outsmarting people by being sneaky but they don't want to actually be clever about how they do it.
On the other side of the issue, you have the curse of being naturally good at games in the SBMM era, which was brought on by those exact people. Yeah, offmeta still works if you're good, but the game becomes painfully unfun because the better you are, the more you run into formulaic opponents who are genuinely, 100% seriously optimizing all of the fun out of the game. And most of the time, in more casual FPS like Destiny 2, COD, etc., the optimal strategy is boring your opponent to death, usually just holding down lanes in a big clump of people. I don't mind losing to people better than me, I hate when I need to wait for two minutes for a match, then get a bunch of 400 ping Chinamen who all have the exact same loadouts and playstyle every time, and then the match times out at 10 minutes, with both teams combined barely reaching half of the score required to win. During peak times for my region. In games that peak at 100k concurrent daily players, with crossplay enabled.
Yeah, during the ping-based matchmaking era and server browsers you also had horribly greasy matches where you get your ass blown out by absolutely fiendish capital-G Gamers, but it wouldn't be every match. Then sometimes you'd get the lobby where you get to be the Gamer playing against a bunch of bads. But most of the time, you'd get a good mix of good and bad players in teams, and you'd generally have fun.
Seriously, why the fuck am I being punished with worse matchmaking times, worse connections, worse matches in general, because I do well in a videogame? Whenever this is brought up you see people coming out with the exact same non-arguments. "oh, you people just want to stomp bad players" If I'm better at a game than most people, why shouldn't I be allowed to beat most people? "well, you can purposefully throw to get easier matchmaking" Yeah, I need to intentionally throw ten matches in a row to get a single match where I don't play at 200 ping and get to have fun. I should do all these workarounds and retarded things, plus probably move to China to not get treated as a second class citizen, as opposed to someone just improving at a videogame if they don't like getting bad scores.
TL;DR: I hate casuals, I hate tryhards, I hate retarded matchmaking algorithms, I hate videogames, I hate the government, I hate jannies. Take me back to 2011.
