However on the positive side caelums flying scouts are great and there flying A2 mages are to die for...
Theres a use for caelums lightning resist flying warriors, guard commander on your mages who do the real army killing. Not that they really need it with mistform/mirror image.
I've been playing Caelum in one MP game for a while, and to be honest, I haven't found much use for the flying infantry. I use a combination of Mammoths and Blizzard Warriors (archers) which is pretty devastating against independents - and against other players in larger numbers. I'm thinking about using Raptor clan warriors for hit-and-run attacks sometime soon.
