If you are referring to not being able to join and people telling you to turn of WSE 2, that is because there one day was a problem with joining with WSE 2 so people now think it is the omnipotent solution to such problem, as far as I know the current joining problem is completely unrelated to the previous ones and all you need to do is wait and try again later, this will work eventually regardless of which WSE you are running.
Also, WSE 2 improves my performances by a fuckton. Usually had everything on pretty low except textures and resolution to ensure smoothness regardless of the circumstances, now I have everything on highest unless it is annoying.
