I had some very smooth execution and kick-ass moments with the Mothership today. It’s definitely an interesting way to take a third base. I need to experiment with getting the Twilight Council before the Stargate to rush +3 instead of only having +2/+1, and being safer against Mutalisks. I guess the key is to be flexible, but I don’t think there are many options to scout if Metabolic Boost gets researched — Hallucinate is too expensive if I’m only sticking to 4 Sentries.
Aside from the occasional Cannon Rush, I’m finding the other two matchups really straightforward. Way too many Terrans are losing to even sloppy rushes that I almost feel bad for exploiting the metagame.
