Kind of thinking about an idea to expand weapon skills and possibly some subskills that may also require being practiced but for much lesser practice cost. Just for an example I will use kick and Archery as an example. This is just an general idea as to how it may work. So for example the kick command may have skill prof add on's with say two sub skills which can be roundhouse that aims at the head and torso. Then say a drop kick add on that does kick damage but also has the possibility to make the target to fall to the ground. Now for Archery there might have say power shot, quick shot. These skills would be for a particular weapon type. So it would kind of be another attack say such as charge but tied to weapon types. Guess this kind of exists in game in a way but this could expand on that.
:edit: Archery quick shot could possibly be a hasted like like skill that is not stackable with hast affect but gives an extra attack to a maximum of 4 attacks. without the slowing down of regeneration.
Archery power shot could increase accuracy for archery when a player is in the back of a formation etc.
This just an idea of what kind of stuff can be done
