When I played BF3 initially I recall always joining a squad when joining a server. I just got the first patch and I no longer do that. How do I configure Battlefield 3 such that I join a squad automatically?
They actually took this feature completely out. I don't think everyone is happy about it, so it's possible that it might come back in the future, or get readded via a mod. For now, though, you'll just have to work around it.
