I know it's for stability issues. But maybe a poll or, a AwEsOmE pUbLiC bEtA tEsT wEeKeNd to stress test servers and determine whether or not they'll be available to the public or needs more cooking time. That sounds fair

its because servers are unstable, and certain features dont even work

Then why not list those up on the website?

It can be several reasons its mainly to make sure things are in working order find bugs testers may have missed and get community feed back to improve the game before release and maybe add reqested features
