Why no love for Caelum?

[Stormbinder]

Well, my personal largest grip with Caelum is that it is the only nation in the game, against which any number of PD are totally meaningless. Single 100gp seraphim with no troops can rout even 20+ PD of any nation with no problem. All it need to do is to cast Quickness + endless line of false horrors. Couped with Caelum's ability to strike anywhere anytime it force any nation who is fighing competent Caelum player to madcastle like crazy.

I think it would be good if either false Horror spell would be made harder to cast (even a little bit, like Fatigue 10 air 2/3), and/or their "fear" value should be sharply decreased, or the price of the seraphims should be slightly increased.
