Leb made it look good due to his failure to deny your only aggressive tunnel. If he denied that tunnel you would lose, you would either have to sit in base or drive out the length of the map. And soon as you drive out he can just harass your base, and will have about 8 comms at least by the time you even get to his base or turn back to defend yours. Tunnels are so important if you have no map control you have zero chance at all, its hard enough vs comms even with tunnels down..
wp tho, you got away with it. So many games won by one tunnel, most important thing for AFG is dneying those tunnels imo
and I'm just wondering did i really just invent a new strat? XDD
