Personally i think those good T's out there are mostly a solid player that does the same build again and again, like mmm and mms, but still they're a tough opponent, so what happens when they can master their race to the fullest? as to what i'm seeing now is already kinda op, good thing they nerf-ed the hellion, cause having that much speed, for 100 mineral, 2 shot, splash dmg, too imba for workers. Just take 1-1-1 for example, try being a toss, figuring he's gonna all in u at 5 minute mark, and try prepare for it, only by them doing mistakes can we win, cause the combination is imba. But I can't blame blizzard, i know they're still balancing the game, just know that the game isn't balanced yet.
