First, I find Novus combat system very good.
Lately, I was thinking of a possible simplification of Novus combat skills. Instead of having one skill by weapon category, I was toying with the idea of having only three skills : melee, thrown, missile. That would give you very broad AB. That way, you are sure that a fighter with a high skill with a broadsword would not be too clumsy with a mace or a staff, which is not ridiculous per se and rather realistic. OTOH, I am aware that it is very generous as a few ranks in a single skill give you a benefit with many weapons. It may be that it is unbalancing regarding character development.
For more specialization, I was considering using talents. For example, a character could develop a affinity with swords or bows by acquiring a talent equivalent in scope with the current weapon groups (axes & hammers, bows...). Each of this talent, rather than give you additional AB, would grant you access to combat moves and/or styles, but only for the considered weapon group.
Maybe it could be better with more combat skills, for example 1-handed, 2-handed, polearms... instead of just 3 broad combat skills ?
Any thoughts ?
