I think the game needs new weapons and armor. Right now the current options are so limited that everyone nearly wears the same thing. So I'd suggest a new line of weapons and armor.
Boiled Leather Armor
Created by boiling minimum Q20 leather at a clay or metal Cauldron. Give it a different color such as a dark brown to differentiate it from the regular leather and give it slightly higher protection.
Bronze Viking Armor
Since this game is supposed to model northern europe. There was I think different models of Full bronze armor created by the various barbarian tribes during the time of the Romans. I think perhaps a different style or two of Bronze Chainmail, platemail, or scale would be nice. Maybe only marginal differences in protection but different styles for people to wear so everyone doesn't look the same.
Platemail
The same goes for platemail. It'd like to see different styles of Platemail with marginal differences in protection. Some different styles of helmets and what not. Maybe scalemail, chain/platemail combo, banded armor which is basically a leather chestpiece with steel plates sewn or bolted in to it.
Shields
OMG Shields. Need I say more? Tower Shield, Heater Shield, Round Shield, Square Shield, Kite Shield. So many different styles to choose from and none are in the game.
Bows- Ranger bow or regular bow? Can we get the composite bow? Crossbow maybe?
Weapons- Maces, Polearms, new swords, Axes, Warhammers? Bronze and Iron tipped spears?
The damage values could vary but you could also program in special attributes. Perhaps spears could have a push back distance on hit? Maybe maces have a chance based on skill level to knock somone silly and raise their attack cooldown back up by a second? Stuff like that.
I know this idea is being presented quite as expect but I am leaving it deliberately vague because only Jorb and Loftar know the capability of the Java client so I don't know just what they can program into it.
