I had an idea for a few weapon classes and sub-classes.
Spears:
My first suggestion was having a new weapon class called the Spear. The spear can attack the same way as a sword, but it can reach farther while fighting. Also i thought of the spear with a charged ability. What i was thinking was that, when charged the spear is released from the knight and is thrown as a ranged attack. Upon releasing the spear it will go through the air and land or hit an enemy. The ranged attack won't go as far as a handgun attack (Maybe it will fly only a few spaces away from the player). Upon landing on the ground after the charged attack the spear will deal different status damage. The type of damage will vary from spear to spear. Some spears will deal fire damage, poison, stun, shadow, etc. I know the sword and handgun already have melee and ranged capabilities but the spear provides a weapon that can deal melee and ranged attacks without switching. I also feel that players will fell a greater sense of freedom and the ability to choose different weapon choices.
Bow:
My second suggestion was a weapon class called the Bow. Obviously the Bow will have ranged capabilities. Now, I know there are already handguns, but having the ability to choose from a variety of weapon types gives players a wider range of weapons to choose from. The Bow will be able to shoot arrows. The charged attack will vary from bow to bow and damage will vary as well. Some Bows will deal elemental, fire, poison, stun, shadow, etc. i was also thinking of a charged attack that would shoot a small volley of arrows(somewhat like the autogun). Or a charged attack that would shoot a single large beam that has the capability to shoot though multiple enemies. I also thought of the bow as a weapon that could shoot ranged attacks not as far a handgun bot maybe more powerful that the average handgun attack.
Others:
The last thing I thought about a weapon as a crossbow. It could be a class of it's own or as a sub-class of the bow. it is the "inbetweener" of the hand gun and the bow. I t will be able to shoot farther than the bow, but less that the handgun. It could also do less damage than the bow but more that handgun bullets.
I hope That there are a few open minded people out there who will support this idea. I also Hope the game people could Integrate this into the game
In my personal opinion, -1 to the Spears, -1 to the bows, but +1 to Crossbows.
Basic logic would seem to actually make a bow more like a bomb, as you'd have to pull back the bow string before firing (and assuming you have a quiver, you have to pull the arrows out of that, too). I.E., it would have to be purely charge attacks.
Spears have been recommended tons of times, there's not much more to be said.
Crossbows seem fine, even if they were completely beside the point of the weapons you wanted to add.
