Let me know how it goes. Seriously, I'd like help refining it. Though tbh, might not be as comparatively good after the patch since one of the main advantages it has over standard builds is early pgrens, and standard builds will be able to get them early anyway after.
Impressions after three automatch games, all of which were versus USF.
Early double stealth HMG made it quite easy to keep your side of the map. I tended to use one in a defensive role and the other to support attacks.
The triple G43 PGrens are retreat wiping gods. It's almost enough to make me worried about the price cut they're getting.
The key thing I found is I had to be very careful with the HMGs: this is a very lean build where every unit (except perhaps the second pioneer) is important. By the third game I was deliberately leaving uncapped points near my base for the HMGs to cap so the Pioneers would always be in front.
While I'm not in a position to judge its power, I definitely intend to keep using it.
