I don't even consider basic socialization the problem. Only the fact that the two options are only "high level play" or "don't play at all." You can't go in and have fun, learn and improve. You must already be a great player or you will be kicked, flamed, or both.

Its one thing in competitive environments, though don't get me started on games that are competitive/ranked only no matter what, but its another in just simple playing of the game and trying to progress in a casual manner. Which of course always reaches its zenith on "meta only" requirements, where anything except the best possible comp/spec/class/etc is made basically impossible to join any groups (again, an issue when group content is the only way to progress).

And its fair if you want to use it regardless, I think otherwise because, as in the other response you got, people immediately assume its usage in a particular way because that's 90% of the usage it gets. They aren't wrong for assuming its being used in that way, which ends up with you needing to explain what you mean by it and ending up using considerably more words to do so.
