I don't recall how exactly the Ninja AF was obtained, but I do remember it being very lackluster. Although finishing the set upon hitting level 50 felt like a reward and added some sentimental value to the armour. I'm honestly indifferent otherwise, the appearance blows AF1 away, and that's what really matters to me, I do get your point though.

I hope the relic/mythic (or whatever they decide to call it) weapon has an epic story attached and not just something that felt rather tacked on like the original.
