A funny thing I've noticed is that the way we build factories has changed completely. It used to be (about 6 months ago) everyone rushed stone for walls, built a big box, and made as compact a base as possible, with little thought to expansion until you reached the walls, and the build a bigger box, and reach the walls, etc.
But now, everyone just builds a factory, and ignores walls at least until spitters / medium bitters, and even then normally just adds laser turrets into robot blueprints.
So, what i'm wondering is: What changed? WHY do we now just build a free base, infinitly expanding without a thought to defense?
What's your answer?
