As you play in the game there was some missing styles and types of weapon use in the game, and so far i've only thought of 2:

Missing Weapon:
Polearm- A weapon that only has a sharp edge at the point of the weapon.

Missing Style:
Throwing weapon- A style of range instead of using only a bow and arrow, you will also have a ability to throw a weapon (Ex. Dagger or Polearm) at the enemy.

if theres more please let me know by posting here.

Thank You

Not really missing the polearm; would be a pain to playbalance. But I think a throwing knife would be cool.

well i've never really seen any use of a pole arm in the game before so yea, would be interesting ^^

There was a game i recently played not to sure what it was but you were able to block and attack with a spear Spartan style. would be cool to gave.

Downside in using the weapon could be a percentage to be disarmed?

To come to think of it, i'm sure it was demon souls

There's a [censored]load of different types of weapons they could have implemented, that doesn't make them "missing", seeing as they were never meant to be in the game.

I'd rather see crossbows, to be honest.

No, polearms are missing. I can think of no other weapon type more appropriate for this game than spears. Between the Norse themes and fighting dragons, this is the one game that should have included them.
