A truly poor analogy. LLMs don't remove anything from anywhere. They consume no shared resource.
It's been wild watching people flail about searching for arguments for why LLMs should be stopped. I'm not even saying they shouldn't, just that I haven't seen a solid argument for it.
That's not my experience, and I'm an elder millennial. The only time tiering up has encouraged me to quit a game was when the higher ranked players were just more toxic. Being challenged can be part of the fun.
That's not to say I think matchmaking is simply better than persistent servers. Having a group of regulars and developing a bit of a server culture is good fun. I guess I like both options depending on the mood.
