When I get flying units, they drop like... flies. Even when I put them on "hold and attack", which I always do (tried experimenting with either rearmost, archers, or none), at the very latest, 2 turns later they are in the enemy's face. Getting creamed. Which is, I guess, how it should be -- I picture flying troops as harrassments for the enemy's back ranks once the rest of their army is engaged with the ground troops. Or to annoy spellcasters. Or for hit and runs (or hit and fly).
But how can I do that? Flying commanders can be given detailed commands, but not so the grunts (harpies, valkyries, etc.). Either "hold and attack" -- or guard commmander. But then they are just a wasted investment.
So how do you use your flying troops successfully?
