My idea has always been that armour material should make a difference instead of being JUSt and arbitrary number. This means that we'd now have plate, chain, scale, hide, etc as types which would react to pierce, cut, and blunt. Wouldn't it be nice if your plate armor had a realistic use? As a plated knight, unless you can pin me (realistically) to stab me through a joint or land a lucky hit your cutting weapons are going to "glance" right off of me. Mail is even more interesting. Blunt weapons are especially effective because mail doesn't stop the impact. But it -does- stop cutting weapons and depending on the size it is very effective at repelling piercing attacks.
This might not be entirely related but the combat speed of C-RPG is a joke.
