I think Caelum's troops have many things going for them.

They have mobility, extreme wall-breaking power, a good number of resistances and they scale quite well with army buffs (quickening + ubiquitous fly is great for a strong alpha-strike).

Their troops might not all be the most battlefield worthy, but they are the greatest in the game at covering large areas.

Admittedly I have a hard time building anything but their archers who are quite good, I use them as a raiding vector (usually lead by a singular Wind Guiding Mage).

For large enemy armies, you have Mages and Thugs to do your heavy lifting.
