Would FIFA "be a ref mode" be a good idea?

Now I know FIFA 13 is coming out and i am really excited. I'm not making some Fifa 14 wishlist but, in upcoming Fifa games or any other EA sports games would be a ref mode be a good idea? I mean it sounds cool but would people take it seriously? Would the referees just be trolls? For example If Liverpool was playing Manchester United in the BPL and there was a player controlled ref, wouldn't everybody just be biased towards the team they like? Even if the ref mode was in depth and if you did poor and seemed biased they could fire you. That would make sense, but then there would be no motivation because winning "Referee of the year" doesn't sound very exciting. Anyway, enough rambling. What would you guys think of be a referee mode? Give me your thoughts and opinions and what features it should have. Or should it never be on a FIFA game? Leave some opinions. Have a good day!
