Okay, this phase 2 was just a warmup for me, as I had no internet connection at home for most of the June/early Jul days -.-
I got to experiment with some really cool stuff, at the last two days I almost exclusively went for 2gate->fast Stargate -> build 2-8 phoenixes (depends of what I am against) and if opponent switches to anti air, I went with all out stalkers, in case of anti-air flyers, or zealots, if for any infantry.
It works surprisingly well. It is worthless to some builds, and it is crucial that you scout anything like a mass hydra or a mass viking, because it feels bad losing all your nice shinies.
God, I love this game. And it is not even out yet.
