I have bad internet, quite possibly worse that any one else's on here. I'm fairly certain it will be worse than yours. I can barely connect to the hub, however I can still do it. But as has been stated above, if you lag on the hub, just don't connect to the hub... no one is forcing you too, and you will never be forced to connect to the servers only through the hub.
Why would we remove an optional feature, that many, many, many players enjoy, that brings people to our other gametypes like ZedChase and MCTF2? It's simple, if you don't like the hub, don't use it.
