I thing mining golems are the most annoying Minor Faction. While the devourer is indestructible, the Miners show up in huge numbers on multiplayer games and can totally screw up your economy if they manage to blow up a planet with a lot of resources. Not to mention their guns wreak havoc with my defenses. It blew up my most crucial piece of defense, a gravity drill guarding the ONLY system that had acess to our home planets. With ion cannons, snipers and a superfortress, that was a virtually impenetrable wall, except that the miners destroyed it. SAD.
How long would it take the devourer to destroy, say, an armored golem? Assuming it could fire at one.
