Despite the massive amount of comments here, I still don't see anyone talking about my personal issue with PvP here.
It's ranked matchmaking. In order to keep things working at all, you have to pair players with players of a similar skill. And this means that fundamentally you don't get a sense of progression besides an MMR ranking. Your win rate will always be roughly 50%, unless you either smurf, or become the literal best in the world. Compare that to tough PvE games, like Doom Eternal, or a brutal platformer, where you can raise your difficulty, beat stuff you could've never beaten before, and generally see your progression. Heck, if you want to relax, just put the difficulty back or crush some earlier levels. I love to go back and learn to speedrun some of my favourite platformers, and that feels awesome. Games like Souls are also great at this, when you have to explore an earlier area and the enemies are just... so easy and satisfying to roll through. Or moments like in Sekiro, when you go into NG+ or just start a new playthrough and crush Genichiro on the first encounter.
And this whole thing is just.. so fundamentally necessary for PvP to work, you can't let new players get utterly crushed by veterans, so it's not something anyone is going to "fix". But I'm not hopping onto an endless treadmill that's never going to give me a sense of mastery. Especially not with so many other fantastic games out there I want to check out.
