I mean, why not? We've already cut the boss's head to make a helmet, so why not take their weapons and claims them for ourselves? We've already have often freaky looking (but sometimes actually look quite cool) armor sets, so what about weapons? I mean, isn't this why vDSA and vMA are such popular grinding spots? Players want cool, unique gears, ESPECIALLY WEAPON! We're so lack in that department.
Talking about cool looking, most weapons in ESO look really boring and frankly, kinda the same. Here's another idea: make weapons skin, so we can change the appearance of weapons, please. Make it works just like costume, but for weapons. Weapon skins will (and should) be awesome reward for complete story quests. Also, ZOS, you can actually sell super dope weapon skins in Crown Store for some extra bucks. I know that the weapon models and armor models have quite a lot of differences, but come on, make ESO great again! What do you say?
