Why no love for Caelum?

[Ygorl]

Another disadvantage of Caelum that I don't think anyone's mentioned, and that makes them somewhat weaker until later in the game, is that their large size prevents more than a few of them from attacking a given target. Most nations can overwhelm a high-defense baddie by swarming it. Not so Caelum. Conversely, they are easily swarmed by hordes of junk.
