I think that players love to hava a great number of choices.
We're planning to have somekind of compatibility with RO?
If not why we bothering with that?
I think that weapons should have unique features.
I really think that there isn't difference between axe and sword (in RO games), the difference is, CAN BE USE BY SWORDMAN or CAN BE USED BY MERCHANTS.
Give the damn AXE to swordman.
Fist (2xlow damage, fast attack rate, double attack)
Knife (low damage, fast attack rate)
Sword (medium damage, medium/high attack rate)
Two handed sword (big damage, medium attack rate, attack rate increases if you miss the previous atack due unbalanced weight)
Axe (medium damage, medium attack rate)
Two handed axe (War axe), (big damage, medium attack rate, can stay locked in enemies body, slowing next attack when succes)
Javelin (1 handed spear) (medium damage, medium range, damage bigger than a bow, need refill)
Spear/Halberd (2 hand) (great range (to body-body attack), good against mounted characters, medium damage, slow attack)
Katar (very fast attack, can use 2 katars, double attack)
Knuckles (low damage, rise fist damage)
Mace (Big damage, slow reload, can stun)
Bow (Medium reload, big range, medium damage)
Crossbow (Slow reload, greater range and damage)
And about whip and boomerang... I think that it's strange. But whip can have a good feature, slow down enemies (grabbing their arm), very painfull.
Boomerangs, throw weapon with medium range and didn't need refill (as arrows or darts)
