Devourer or Warrior on Nocturne?
I want to pick up Nocturne, and it seems to really vary whether people go devourer or warrior. I personally thought Warrior would be better because Nocturne has AD scalings on his Q and ult, and despite his innate attack speed bonuses, he doesn't really have an on-hit element for Devourer. (Like Shyvana E, for example) Yet Devourer Nocturne still seems common...
Thoughts?
EDIT: What 6 item build(s) should you go on Nocturne?
