I'd like to see soemthing like this:
These weapons can be used with either of the two profiles below. All models in the unit armed with Elf Bows must use the same profile.
Normal shot: Range 30", Strength 3, Special rules: Volley Fire
Power-shot: Range 30", Strength 4, Special rules: Move or Fire, Slow to Fire
This means the unit either gets to move and shoot, or it can remain stationary and either make a Volley Fire attack or shoot with improved Strength.
