Miss Fortune could use a slight adjustment.

Over the past week or so I have had an interest in playing Miss Fortune, both as and ADC and as a Mage, and I have come to like both of these styles of play (I'm in love with Mage Fortune). I have a great time leveling, farming, and getting items. That is until all of a sudden I need to get a Magic Pen or an Armor Pen item.

With how her kit is currently, if you are stacking one type of damage (AP or AD) then the type of Pen you need is the opposite.

*For example, I like to go Mage Fortune often enough, but to get the full benefit of my Double Up (Q) and Bullet Time (R), I would have to build Armor Pen because both deal physical damage.

*With going ADC Miss Fortune, you stack a lot of AD. Her Impure Shots (W) scales off of AD and applies to her ultimate, but this is all magic damage.

I would prefer to see Miss Fortune build the type of Pen items that correspond to the build type she is going, maybe make Impure Shots deal physical damage and Bullet Time deal magic damage.

That being said, is there a reason that this is how she is currently? Would she be monstrous late game if these would change?
