Miss Fortune's all over the place...
tl;dr: All I'm wondering is this: What is going to happen with Miss Fortune? Her E is only used for the slow, but makes her stop to cast it, her main early harass tool is tied to a late game stat, and her recent buffs push her to an auto-attack playstyle, but her passive encourages switching targets which is strange for an auto-attacking adc. She should be a spellcasting, teamfighting adc. It's also frustrating that her average strength is tied to lethality's strength.
I play MF both as an adc and as Mage Fortune. To my knowledge, Mage Fortune was never that popular, but it is fun to play. This post isn't only about Mage Fortune, but a lot of the nerfs/changes made to her has hurt that playstyle. It would be one thing if the changes made sense, but many conflict with what her playstyle should be.
The E nerf (90 base damage at max rank) during the adc rework made that ability only a slow zone. The reworked q, to reduce it's power with lethality, makes her lane bully identity weaker. She's being pushed to an auto-attack focused adc, but her passive is only good for the first shot unless she's switching targets, which an auto-attacking adc shouldn't do. Plus there will always be better auto-attack adcs than MF. If her passive could be reset by her q, regardless of whether it bounced or not, that would make more sense for that direction, but wouldn't make sense as an ability.
Honestly, it feels her kit is made of two different champion ideas. Her passive and w feel good for an auto-attack focused adc, (like trist), but her e and ult feel better as a teamfight oriented adc. Her q could fit onto either, really. Looking at the other adc's, they all have good identities that fit them. Trist is a tower taker and in your face, Sivir excels at wave clear and teamfights, Cait is a long range, zoning adc, Jhin and Ashe are long range utility, though very different, Kog'maw is a time bomb of hyperscaling, etc.
Her old kit had better synergy with itself. It just had problems with scaling. Impure Shots could come back and replace Love Tap as her passive to give her better teamfighting ability. It could be a reason to lower damage on her q bounce and ult, which many people complain about when she's strong. Her E would have a better use than a slow zone, since it would apply stacks of Impure Shots, and it would give her magic damage on her kit again, which I always thought was really cool for an adc. Only Kog'maw and Corki really have that.
Just so long as she scales better than pre-rework, but isn't overbearing with chunking half your health with 1 q in lane. I like her early lane bully playstyle, but there's a limit. She could even be viable mid with these changes, like corki and, to some extent, lucian.
