Hey this is my second non meta guide I have ever made. This time i'm shooting to give you guys an idea of how viable AP Miss fortune can really be. To me, she is like a syndra who can kite people but instead of dropping huge damage on 1 target she spreads her damage over multiple targets. I've always been interested in MF but i could never enjoy her bot because she blows through her mana and doesn't fit in this meta. Well, truthfully, she secretly does fit in this meta. Assassins mid seems to be in right now and MF makes it very easy to disrupt their play style which is pushing lane and roaming. She pushes lane very fast meaning the mid will need to stay in lane or lose tower hp. If she kill lane opponent, pushes lane far enough, or makes opponent back, she has a lot of Move speed to roam.

Sorry my guide isn't Pretty like some peoples are

Pros
Strong wave clear at level 8 with only a sheen
strong harass with high mana regen early game
high burst damage late game(faster out put than adc MF)
hybrid damage that is hard to build against
Liandry's chunks tanks and squishies when you put your "make it rain" on them
very great dueling power with full item build, never feels caught out in a 1v1
Great roam, 450 ms with just tier 2 boots and passive
Can get kills easily at level 6 if the enemy is under half hp by using E and R


Cons
Super squishy, doesn't build any tank items until hour glass
Needs to have a team comp that can allow for peeling or setting up for her ult
can get harassed by tanks who build slow reduction
easy to focus(basically an adc just an apc)
has no defense runes or masteries
Gets countered by champs who can all-in in lane very easily
Can be CC'd out of her ult
You will not find a game/people will troll you for playing her mid

To Explain these runes, We need to dive into the reason why we don't like MF in mid normally. Her mana costs are extremely high and her e damage is extremely low until late game. So how do we fix that. Throw caution to the wind and say to hell with an extra 6% dmg reduction. The out put you can consistently put out will far out waver what you would get taking the hits instead of dealing them. This build will make you a lane bully, u need to play aggressive.
