The last bit is what killed world of Warcraft for me. When it changed from a world with the same people in it everytime, to automated group finders combining every possible world anyone could be in.
Not only will you never see those people again, for a while it was literally impossible to talk to them or friend them.
When they put out classic wow again, they updated it to have all these "new quality of life" features.
Thank god for private servers.
