Guild Wars 2

Infinite Light, among other weapons, still needs an icon to distinguish it from regular non-unique weapons.

There are a lot of weapons that still don’t use unique icons.

I’m pretty sure its been said the devs are aware of all of them and are slowly working on them, but they only have a couple icon artists so its a slow process.

EDIT: Just noticed my Krait and Adamant Guard (Charr T3 cultural) weapons have new icons as of the April patch, so yah, this is still an ongoing process of adding more icons to weapons.
