Guild Wars 2

As far as I know, norn cultural armor is the only kind of armor that offers bonuses to power, toughness, and vitality. If norn is the only race that can access these stats in their armor, wouldn’t this create serious balance issues since this stat combination is extremely popular and only norn would have access to it?

Or is there another armor set that gives these bonuses, maybe from a dungeon, that I don’t know about?

The stats of cultural armor/weapons isn’t really important. They cost ALOT and is not worth the money/karma. Getting cultural armor or weapons would be for the sake of transmuting the looks only.

Better armor can be obtained via armorsmithing for example.
