If there is a game you know you wont be winning just play TIE and make sure to increase your ent and thus strengthening your chances of winning in the next game.
In fact, I would even advocate playing every game with TIE and noting how your team's ratings with a TIE and 10 enthusiasm compares to where they started. When starting out, normals should be rare and CTs ultra-rare, and hopefully remain that way.
