Miss Fortune is being given a small visual update, she looks good but mainly her hair and her facial features are becoming outdated and less defined.
Miss Fortune is also getting a small buff/change to her E. Nobody knows what it is, but as someone who plays Miss Fortune mostly daily, I hope that it gives her more utility since she has a ton of damage already. Who knows, maybe they'll give her an entire new ability. But I fear the day she is given a dash will be the day she's constantly played in the LCS or something due to how powerful her damage can be and while she in general might fall of late game, she still can do 48% of her bonus AD in each auto attack damage dealing magic damage (Hard to counter her since she does a ton of mixed.) and her early - mid game is insane.
