Miss Fortune's identity got destroyed by this rework
I'm not saying it's a bad rework; in fact, I actually think it's one of the better ones (much better than Quinn's, for example). But, what MF used to be was a lane bully with some of the highest base stats in the game. The reason she was so good in lane was because her kit included everything: poke from her Q, burst with AA + Q + AA, sustained trading with impure shots, and a pseudo-execute with her ult. That being said, she scaled poorly into mid-lategame because her Q and ult reduced her DPS and her AS steroid wasn't quite as good as some other champions'.
What I think Riot seems to be trying to do with her update is to give her teamfight potential to capitalize on her lane strength (much like the darius rework). However, the new update seems to have removed her laning power entirely. Her base AD and AD scaling were heavily reduced, impure shots was removed: in exchange, she received love tap (which really doesn't help except for your first auto) and an ult that does more damage over a longer time.
Miss Fortune is by no means weak; her ult deals upwards of 3k damage and 110% attack speed is amazing considering every other champion with a comparable steroid has low base AS and AS scaling. Still, I don't like the way 5.22 changed her identity from lane bully to yet another lategame powerhouse. My suggestion? Nerf love tap, nerf her ult, move the power to her Q.
