That's not how we work, and we do have a testing server.
And a testing branch of islands and a stable branch of islands.
Maybe the game needs to highlight that a bit more when you're creating a character. Clearly tell people who are going to a testing island that they'll see new features first, but that they can also expect a larger number of issues due to that. From my experience there are quite a few people who aren't all that clear on that.
