I've got some pretty solid fundamentals in my game now so I can counter a lot of different scenarios. This morning I got stumped with Ravens. He basically fast Ravened me and I could never figure out a counter. I stuck in the game long after I lost, just to try different techniques. Those auto-turrets fucked my shit up, especially in the early game when my units had no armor. My poor little roaches just fell apart. I've been trying to look online for suggested counters but all I see mentioned is Hydralisk... but I had tried that before the roaches! Those damned turrets have too much health for Hyrdas to go toe-to-toe with them; zerglings and roaches die too fast to tank for them. Any advice would be appreciated.
