Just played me T vs Z twice... first game I tried to build up army thors with marines, marouders, 1 battle cruiser almost 2-3 from each of the units and he came with lots of hydras, lings and mutalisk he owned me... Next game same races I build 2 barracks with the second add-on to the barracks so I can build 4 marines at once and I attack him with 17-18 marines and he did have 2 lings and 1 queen...and just in the moment I was attacking he actually build up 6 lings and other 4 after those, as I was destoying him he was building up structures, so could add a little defence at begining to the zerg my opinion. Good job guys, keep up the good work.
