Had a pretty nice entertaining match today.
Match starts, I say "gl hf". He says "Fuck you asshole". I think ok, whatever. This is PvP. I scout and we get our gateways up around the same time, but I end up having way more zealots than he does. While I'm at his base with my zealots, I notice a pylon by the front of my base, and immediately destroy it with the newly created zealots at my base. As I destroy his base he just rages at me about how I was cheap because I rushed etc etc.
I don't think players really utilize the new race specific macros (at least at my level of play :lol ) as much as they can. Chrono boost is a god send, as is the queen. Haven't used mules too much, as I haven't play too much terran, but I imagine they have the same boost on econ that the P and Z have on unit production.
