I was under the impression that Golems were not utilized by the AI, unless "Golems - Hard" has been enabled? I'm playing with golems set to medium, against 7:fortress baron/7:entrenched; in my two latest games (5.022), I've had two encounters with Armored Golems. The first one sent humanity down the drain, but I was more lucky with the second one, thanks to it being somewhat less particular about its approach vector.
As someone still new to the game, I might have misunderstood the AI:s use of golems. Is this normal - or can I pat myself on the back for surviving something I wasn't meant to battle?
If memory serves, both golem encounters happened somewhere around 6h mark with AIP ~400.
