Thank you for posting the unit stats and hex data for Warsong. I very much enjoyed reading information I knew nothing about.
I'm surprised that enemy casters often have more than one spell. I never see them cast anything but their big nuke, until they run out of mana.
When I get the time (and motivation), I'll tinker with unit stats and spells a bit more and find out what the enemy AI can handle a bit better.
I'd like to finesse MP-drain cheesing tactics, increase boss difficulty, and tweak less desirable units - especially reduce indoor penalties globally on mounted units! Your choice to give Tiberon the Dragon Knight promotion was an interesting alternative, on that note.
On the subject of your mod, the Excel sheet notes the changes you made, but the amuseum page doesn't include that in its description. (Similarly, it doesn't say that it's a kick-butt Warsong modding resource.)
Also, your mod is mentioned here:
