Miss Fortune's Ult
I know Miss Fortune hasn't been played very recently, but I've noticed for a while now and thought I'd fill in on her ult. In the description of what her ult does, it doesn't actually do it.
ACTIVE: Miss Fortune channels for 2 seconds, spraying up to 8 waves of bullets (6 bullets per wave) in a cone in front of her. A wave is fired every 0.25 seconds, dealing physical damage and applying Impure Shots' passive magic damage and stack to all enemies within the area.
With that being said, Miss Fortune's ult doesn't scale off AD throughout a game. AD being in red and AP being in green. While in game it says (+0) in green followed by "physical damage", in the description of her ult. I've tested this by buying some AP to see that it would scale off of, and yes, it did.
