Thank you for delivering your point better, more concise, and in a non-disrespectful way, something your community manager couldn't do. I don't mean to sound like an ******* in saying that, but if your community manager is unable to respond helpfully and without being a smart-ass, that's not good.Everyone's got a bad day now n then.
But more on point, we have moved betas to live without a new beta before - when we thought it to be ready. And we will do so again - because we do want to bring the MP content to players, but we don't want to split the MP playerbase unnecessarily. (More curiously we even had 2 betas at one point.)
As for our beta release approach - we have our internal processes and guidelines. While the beta is less stable, it is still meant to pass certain criteria. So we won't release it with known (frequent) crashes or other significantly game breaking issues.
