You might have to clarify what you mean by the point I'm trying to make with Impure Shots: I think the ability's really good and is unique in the sense that it automatically allows Miss Fortune to ramp up her damage output as fights extend, as opposed to the champions you mentioned whose bonuses are more constant.

The idea behind Mage Fortune is that, while she does depend on Impure Shots's ramp-up for a large amount of her power, she's more focused on laying down powerful but spaced-out nukes to the back line, as opposed to ADC Miss Fortune who wants to keep on fighting for as long as she can. I agree the Tristana rework made her AP playstyle a lot healthier, and while she's not in the best spot right now, she has the potential to be extremely strong and full of counterplay at the same time, which is also what I wanted to achieve here (Mage Fortune would telegraph her intentions heavily as she'd try to set up her nukes via a EWQ combo).

I don't really think Strut really counts as a "defense", considering it gets deactivated by taking damage and therefore is of little use during proper combat ( offer an even steeper movement speed bonus and don't really qualify as defense). I agree a lack of mobility is one of MF's weaknesses even now, and for that reason I think keeping that weaknesses while buffing what makes her stand out (namely, her ramping AoE damage) would improve her in a manner that emphasizes her uniqueness. With that said, I did provide a substantial buff to her base mobility (she gets +15 base movement speed), and I changed her E to let her cast it while moving, which would help her maneuver better in the middle of combat, something Strut doesn't do at all.
