yes, you keep the race if this happens. get back 2 your proper team, ask an admin for help if needed and take your race back.
Fuck no. that's beyond a retarded idea... cause one, people like playing certain sides depending on the map... and 2.... even if you could only select auto select... you will still end up the majority of the time with 1 team doing far better... meaning... people will still qq the teams aren't fair.
