By ignoring the game logic and choosing totally randomly from the whole list of sites. Im just plain over the edge as far as chaotics.
Its like my chaotisizer for maps that assigns random units. It selects equally from pretenders, summons, commanders, and units. A slinger could be the commander leading a squad of monolths with 5 horrors as guards. I pushed for a SemiRandomizer which does it more logically and I love what Ballbarian is doing with it.
But I still have fun with the chaos.
