Play very little multiplayer, bronze league maybe 10 games or so, won every single game vs terran, lost every one vs zerg. Watched all terran vids and resources and strats, but don't quite understand what counters banelings busting through my wall in. couple games i got zerged just as my first siege tank was rolling out with siege mode upgrade. Switching it from barracks, while constantly pumping ground units and walling off top ramp. Should i wall off with bunker with supply depots behind them and pushing fast siege mode/tank backbone behing the wall in, so banelings kill bunker instead with the wall of supplies still behind it. Last time banelings just ripped through the wall and lings overwhelmed the ground units, and the one tank didn't siege up in time as it was rolling out of production. Does going mech, with minterals pumped into helions behind the wall in with siege tanks, work better at fending off first attack, followed by a hellion counter attack, with a banshee follow up? Keep losing to Zerg on first rush.
