When you leave a wz because it's a lost cause, all you do is give up your coms, cash and valor. The next person that joins that lost wz does not have time to build up there stats to get anything at all out of that wz but a loss. Yes, you get to queue for a new wz faster but odds are you wont get into a fresh wz, you'll just replace some other quitter's place in a lost wz. Until, BW puts in a penalty for leaving early I'm asking you to consider these facts.
