Cannot log onto Mists of Pandaria

Everytime I try to log in on the main menu, it says "Connecting" indefinitely
Should I redownload the client again?

I've also been having this issue, I have redownloaded as well but it didn't seem to get anywhere.. aside from the infinite connecting window, it will sometimes say that I need to connect my battlenet account.. I'm not sure where we're supposed to go from here

Warmane realmlist guide and using username to login, not email, goes a long way. If the connection issues remain, trying VPN could be the next step.
