You know what I liked about Miss Fortune?

She had a little bit of consistency. Her W was actually strong with the ability to reduce healing. Any comps or bot lane that even tried using healing would actually have to out play people instead of healing to win. This made MF in her own little spot, yeah she wasn't anything great but she had the GW that you wanted with the ability to be a decent trader as a lane bully. Now when I look at MF she is almost a free kill. Her passive hasn't changed, it still becomes useless after a minion shot or while in combat and once her passive is down she is the easiest ADC to catch. Her Q is still very lack luster, good early and garbage later. The "buff" that they gave it is so situational that I found my self getting CS with it almost always. E is still a massive waste of mana that has a cast time, the slow is still not noticeable, you will get caught anyways. W was nerfed massively, no more Grievous wounds but at least you can refresh your passive! AS buff still unchanged and stupidly weak for an ADC that has to rely on autos for almost all of her damage and has 0 mobility. I can live without her Ult being buffed but honestly it isn't anything worth picking over another ADC.

So with all of this Miss Fortune is in a terrible spot right now. She has little to no identity as she cant fill 1 certain role. People might say she does everything okay but not a master at anything. But that is the problem, she at least used to be the choice to reduce healing, now she does poorly because almost every other adc has a kit that gives them a clear strength past laning phase. A MF that is not massively ahead after lane will not bring enough to the table and will get caught easily.

TLDR: Miss Fortune needs a lot help. She has no identity, the last "rework" was a massive nerf with the removal of her GW. She is still the easiest ADC to catch and has no steroids if you will to help her out. Almost all of her abilities have flaws which needs to be addressed. The last patch was a big middle finger to everyone that liked Miss Fortune and actually played her to some success. I still think Riot is a bunch of mains.

Unrelated : I also don't like the new auto attack animation but meh.
