Allowing Team Change on Core Mixed server

I mostly play on the Core Mixed server because it has more variety (game modes/maps) but something that gets annoying is the fact that you can’t manually change teams. This can create problems if you’re say playing Dom and one team is full of people and the other team is one guy and the rest are bots. He pretty much has no chance. Whichever side you’re on, if feels like a lame match and can be very frustrating.

So, if possible, I think it would be great if we could change teams mid-match on the Core Mixed server.
