Whilst you need to make an Engineering Bay, which costs 125. Also, you need 75 to make an Evolution Chamber for Zerg to get their Spore Colonies, which takes less minerals to make then the Engineering Bay and it builds faster. You can get spores close to the time you can get Turrets, if not faster. So you have to make an SCV, Wait, Build an Engineering Bay, then build Turrets. Zerg can have Creep Colonies waiting to be morphed right as their evolution chamber completes. Erm...if you have decent micro, pushing B, C on the area you want to build then doing something else and going back when it spawns to push S shouldn't be that hard. Then again for you it might be. Ir's easy enough for me. Hotkeys rock. Your numbers mean jack when I can make Colonies faster then you can make Turrets. Unless you want to rival me by wasting minerals on 12 SCV's which take food as well to build 12 turrets at a time. I can make 12 Drones in one swoop, and morph them into creep colonies. Then into Spore Colonies. While it does take more time, they are better stat wise individually so it more then makes up for it. Sure, not many Zerg Players online like Air Defense. If you know how to spread your creep right it isn't a problem though. ^^ It wont matter eh? 200 More HP. Faster attack speed. It'll hold the enemy off a little bit longer and do more damage. Please explain to me how this hardly matters. If you can, I'll quit debating this issue with you all-together. Last I checked, 200 HP units died faster then 400 HP units. Focus Fire does make quick work of AA Defense. But your Turrets will die before my Spore Colonies will, I guarantee that. ..Funny, because I always see a Zerg Player building more then 3 drones out of larva to make creep colonies or something else instead of ''pulling them, off the mineral track''. Remember, Zerg have hatcheries. Meaning I can build my harvester faster then you can build yours. Even if you make a few more Command Centers, I'll still out produce you in workers to morph my colonies. It may not be as fast as 2 SCV's on Turret Duty, but it's a quick fix. If you're like me and make lots of hatcheries, you can possibly match a Terran Player in speed as far as building the AA Structures is concerned. It does depend on how many you're willing to make. I like to make plenty, meaning I wont die as fast as you do. You could make more turrets but they die much faster to Focus Fire then spore colonies do. Again, Zerg can make 12 or more drones within 30 or so seconds, so numbers for Spore Colonies don't really matter when you can pump 12 at a time. Or hell, even 6 at a time. You get what you pay for. I would say so.
