NL should let someone other on semi to play (at least one sub on second map, because they had 12 scores lead.) but it's only my opinion. They probably didn't want to take a risk because VS is good on semi. Good job anyway.
@Sasik, yeah TS can help a lot in tactics on 'small' maps like GW. It's easier to say where to go, where the enemy is (for example 'go from down to score, there is an enemy at PU'), what to do, etc.
