Swarmhost?

  (Edited: )

Swarmhost doesn't seem like an ideal tactic but I haven't seen the game yet. I'm almost certain ravens hard counter SH because detection + seeker missile. Vipers could be deadly if microed correctly, I hadn't thought of that. I think you basically have to keep the Zerg to 2 or 3 bases. My friend said that blind baneling detonation could help eliminate ghosts even without detection, although I think that might not be feasible and would require insaaaaaaane micro ability. Anyway I saw the daily you were talking about. Personally I don't think skyterran has to be that passive, there's very little the Zerg can do early/midgame.
