I kind of lost you in the formatting of your post, but you are correct. Miss Fortune really needs some love to bring her up to par with other ADC's in the current state of the game. She has so much potential to be a solid pick in the game, but her aged kit really needs looked at and updated to bring its power level up to what other ADc's have at the moment.
Now, I really don't want them to just throw a Dash onto her, and make her Graves/Lucian 3.0... I think that's a terrible idea. BUT I really think riot could do some things to tweak her kit to give her a Niche Spot in the ADC market.
Start off with making her Passive Not be broken by minions, give her the Garen treatment.
Second tweak her kit to make her the split push bruiser ADC of choice. She's already fast, Riot should capitalize on that gameplay by updating her E, so the slow applies for the full duration for anyone hit by it. And make her a little beefier so she fits into a split pushing role.
Also do something wth her ult to make it worth casting. As it is, once you reach 4 items or so, it actually starts doing LESS damage in most circumstances, AND it makes you a sitting duck for 2 seconds if you channel the entire cast. I really Only find it useful for securing kills in the laning phase from 6-10'ish. That's not a good place to be for a toon's Ult.
Come on Riot, comment here and give us some feedback on our favorite Pirate Hunter.
Oh and bring back her Pirate buff. "Yarrrrgh I'm a pirate hunter!"
