Well I will probably confront you with my Man army of 150 longbow
XBow are better against armored target but a bit too slow on the fire.
Flyers could help, and any spell like rain and storm will hit you, especially as your mages are also fire dependant.
I guess my own flagellant with an Air 6 blessing would be helping too.
But massive archer tactics are good on my book.
Also battlefield spells with an army of mages with cloack of missile could do the trick.
