Well, it's pretty apparent Miss Fortune sucks, and she is going to suck even more. Post your ideas on what you think should be changed.
My possible solution: Make her Q split off into a cone after hitting a target. Like a mix between Graves' ult and Lucian's Q. (I know it's not all that good, just a thought. She could probably use more identity in her kit too)
Zakennayo2 votesPassive -> Ammo Pouch: Miss Fortune carries ammo with her that deals bonus damage, Ammo is used for abilities. Last hitting minions returns 1 ammo, double for Siege and Large monsters. 5x for enemy champions.
Max 10-20-30
Q- Leave the same (Cost 2 bullets to deal bonus damage)
W- Fires an oversized bullet at target direction that sends Miss Fortune flying back. Bullet cost 5 for bonus damage plus scatter shot which causes the bullet to break into 5 smaller bullets that explode dealing AoE damage.
E- Throws bullets into an area that slows enemies in the area and deals DoT. Cost 5 bullets to stun
R- Unloads all bullets left in pouch to deal massive damage in front of her.
Wasn't thinking as I typed this. Just thought of what I would love to see in an ADC champ while attempting to keep some of MF's current ability identities.

I really like this too, I think unloading ALL of her bullets for her ultimate doesn't make much sense. Would she only be able to ult with maximum ammo? Would the damage scale with how much ammo she has? Would the duration change? I think her ult should really just have the mana cost, especially since it often gets canceled and if it does, she is often cc'd and with no more "ammo" for bonus effects.

No,Yes,No, No, Last hit and get some back.
Basically I want to try to get Riot to force players to Last hit over AA'ing minions.
Variks the Loyal2 votesAllow her to move while AA'ing, at a reduced speed, while Impure Shots is active.
Makes better kiting, synergizes with Strut, might promote niche builds (Boots of Swiftness OP), opportunity for cool run 'n' gun animations...

Lucian is more Gun Fu than Run 'N' Gun.
Khell DarkWolf2 votesDouble-Up [Q]:
2nd bounce is actually a conic shrapnel spread (aka mini graves ult)
Strut Removed - Replaced with:
Shock & Awe:
Shock: For every 5% of Critical chance, you gain 1 point of magic penetration Awe: Every xxx amount of bonus AD (?), you gain xxx amount of bonus Mana pool (?)
10+ flat movement speed is added to base stats to make her more consistently "nimble" and centric to a combat kit.

I'd prefer if Riot nudged her a bit away from the hybrid MF. Imo all her abilities should be physical damage and the abilities that have AP scalings should be much smaller AD scalings. A nice way of buffing her. I like the passive change, but I think instead of magic pen it should be armor pen. The mana is fine imo. Putting ALL of these changes might be a little overtuned but it could be easily put in line with some damage nerfs as it's not like MF has any gamebreaking mechanics like Kalista, she is a pretty simple champion.
5D Paragon1 votesI love AP MF though. So strong :(

That is kinda her flavor though. Having the AP Ratios isn't BAD per say, but it doesn't mean any she gets goes to waste.
I already explained it to someone that you could TECHNICALLY buy a Zhonya's for the item active and still get SOME benefit from the AP.
Not saying its good to do it, but it isn't wasted stats like buying sheen with mana on a resourceless champion 
.

Yeah, the thing about giving her Armor Pen instead of Magic pen is that the armor pen route would push her into a broken state situation.
The idea was to be subtle and keep it niche coherent to her kit which benefits her Impure shots (and anything else in her kit) in its current form. Cause that literally is her Identity.
If there was an ADC that exclusively got free armor pen, it would be a contested pick in LCS for shredding people apart. I'm perfectly happy (and I'm sure other mains are as well) that she isn't banned/pick every single game but has a chance to have some spotlight to still be picked by those that actually use her. Otherwise we would never get to play our Miss Fortune. (Example cause I'm still reeling from the Sejuani usage from LCS)

Aye, I agree with this.
5D Paragon1 votesQ - Leave the same
W - Reduces Q's cooldown by half for the duration. Increases attack speed by 20/30/40/50/60. The second shot of Q will explode into a small AoE zone, like Tristana's bomb.
E - MF flings a flurry of rocks into the air, that drop down and slow enemies hit by it for 15/20/25/30/35% and deals 50/100/150/200/250 magic damage. Small CD, Crescent shot like Dian's Q, except going outwards like this o () When enemies are hit by the rocks it applies a slow debuff that stacks each time MF hits them with this ability. At 4 stacks the enemies are stunned for 1.25 seconds.
R - Keep the same, except it gradually slows enemies movement speed by 2% per .25 seconds they're in the wave.
Passive - MF gradually gains movement speed when out of combat up to a maximum of (+80/+120/+160). When damaged by an enemy, her passive movement speed is decreased by 20. When she exits combat, it begins to gradually increase again.
Ratchet Fortune1 votesI main 
and some others but all I really want, (since she doesn't apply grievous wounds AT ALL so she won't be applying it as frequently with her W), is for the attack speed to be either 30%/40%/50%/60%/70% or 40%/45%/50%/55%/60%.
Oh and also minions not being able to cancel her passive either at all stages at the game or at certain levels, but that might be too much to ask.
Personally I think grievous wounds was a unique feature to , (like her ultimate laugh), and since her Q goes through someone, the 1st target hit should be affected by grievous wounds for maybe 2/2.25/2.50/2.75/3 or just a flat 2-3 seconds based on the targets missing health. But I heard they will be removing grievous wounds from the game from everyone and everything so that won't happen.
