To previous replies :
Flying has a *big* advantage over overland strat move, it allows to pass any terrain without having to have "xxx survival" ability.
So any Caelum/Devil player can use 1 army to as much effect as 3 or 5 landlubber armies, attacking the weakest one in turn without possible retaliation. And if the landlubbers regroup you can wreak havoc everywhere else and use mass damage spells against them !
And no, M Winter hasn't any noticeable effect on devils, nor against Caelum? Only FftS is effective and only against Caelians.
As 1 turn is 3 months long, I don't suppose strat move represent any unit running/flying for the whole season, but is rather an estimate of an army ability to move in an organized fashion, with supply train and so on. So "Flying" shouldn't be that much of an advantage .
Powerlessness of PDs is another balance issue indeed
