Guild Wars 2

A great axe would be awesome.
But besides that the weapons I would love to see:

Halberds
Spears for land combat.
Crossbow.
Mini Crossbow, so you could dubbel wield, might be usefull for thieves.
Whip.
A rifle for rangers.
A net shield, Like you saw in gladiator fights, to cripple your opponent.
A morning star.
And of course more polar arms.
Pretty much what I can think of atm.

Well in matter of fact, they are for your whole account. When you use the skin it will go to your achievement panel, where you can take it out again for as much as you like. It’s actually an unlimited supply of weapon skins ^^

Just press H in game and then go to your achievement panel. And you’ll find them under summary. Click the weapon and then take out, voila you’ve another weapon skin.
