After much blood, sweat and tears, I completed the game through the Revenge (Hard) Route. Ragnar, the Reikland Knights and Grudgebringer Cavalry were indominatable, but the artillery and Wood Elves did stupid amount of damage.

The Grudgebringer Infantry also managed to gain 2000 exp and were pretty nice throughout the campaign as support.

OP Signing off after a good many hours poured into this hideously difficult but wonderful game.
