First impression, im really enjoying it, nice mod.
Chose the Undead faction for my first run through the campaign. Must say excellent skins, making for some epic battles. I like the necromancy traits on the generals, being able to replenish my armies after victories is very well done, in terms of balance i thought a counterweight could be something like lose the general (the necromancer giving life to the army) then lose the army - might even things up for balance for the other factions.
Carn't wait to see what you do with the Skaven faction when it comes along (by a mile my personal favourite back in the days when i used to tabletop) Skellies vs Skaven will become the toughest of my future campaign choices
