So, I have a question...why are all spears in NWN two-handed weapons?
All throughout history, when spears were used, they were used both two-handed (as in many Asian cultures that didn't typically use shields), and one-handed, usually coupled with a shield (typically in early warfare around northern/southern Europe, western Asia, and Africa).
Most two-handed spears were actually much longer than what is depicted in NWN, more akin to pikes than spears.
It sure would be nice to have spears in NWN made into one-handed weapons. Then one could play, for example, a Greek, Celtic, Norse, or similar character and use more authentic fighting styles (spear and shield with a back-up weapon). I can't imagine this would be unbalacing in any way...one can already get a variety of one-handed weapons that do 1d8 damage...spears just do it piercing instead of slashing or bludgeoning.
Is it possible this could be implemented? I know if it were, I'd probably make myself a new character, just to take advantage of the coolness factor...
