This happened for me too with Stark when I first ran it (as Stark Terminus). I felt myself much more eager, willing, and open to speak up.
That build, Stark Terminus, really did feel like I’d ingested caffeine.
That was years ago, but I still remember it. It was the reason I started ordering everything in Terminus or Terminus Squared build for 3 years. Once ZP came, I decided to go back to Standard and grow with that for a while. But I am thinking again.
