Simple (?) question: is it possible to change the combat dice size? (Ie. the range of the random number generated in combat. IMO it is too high compared to the General's Skill's influence...)
I am afraid everything is hard-coded in the game engine. But I suppose you could double the Martial stat on all characters... if I recall correctly it is not used for anything else (in the engine), so you could halve the effect in titles etc. and end up with the desired effect.
