They do seem extremely overpowered compared to units in Civ IV BtS, but you should also keep in mind what you're comparing them to in Fall From Heaven. It takes a long time to get Blasting Houses and even then, you don't get the promotion on all of your golems. You only get the promotion on your golems that are built in that city. All the other golems and all the golems that had been previously built don't get the bonus. Also, "real" mages with Combat promotions pass the "combat lite" promotions on to their summoned units. Golems get "combat lite" from Barnaxus, so the Fireballs always start without promotions. That's not an enormous difference, but it is there. Finally, every civilization in the game has a point at which they are overpowered. Clan of Embers has it at the start of the game, as do the Doviello. Amurites have it either at Sorcery or Arcane Lore (depending on how you play them). Baselraphs are overpowered at several different points in the game (with significant differences based on your neighbors' traits and based on the map). This is just the Luchiurps' time to shine. ...and honestly, I'm not even all that impressed with that point. If I have 20 fireball throwing golems, I'm still going to have a big problem facing a lot of other civs who are at a similar tech level just because they have something that's even a little scarier. Yikes, I just thought of something. Mimics vs. fireball wielding golems. Now that's just silly.
