As far as i know many new games appearing on Steam are as near as unplayable because of bugs and shortcomings. And it takes time to fix them all. Let's hope for the best and do what we can to force the developers to finish their work.
In Dota2 you can select and deselect every region of the world no matter what region you are in. Proven wrong.btw, i dont think they will make a single region for all players like we are requesting from them. it's how steam works, in CS:GO for example it's the same thing with lobbies based on regions
