Guys, chill out!
This is a major patch in terms of features. If you were expecting perfect server performance on patch day, I have to assume WO is the only game you have ever played online.
Give them 2-3 days to work out server-related issues, You can be sure they are testing out all the new features server-side as well right now - just as you are testing out the client-side changes.
Be happy that most of you are able to go online at all. I wouldn't have been surprised if the servers would have been more down than up the first 24 hours after such a patch.
