Miss Fortune would benefit from some gameplay improvements
As a champ MF has some of the lowest agency in the game. No hard cc, initiation power, defensive tools etc. She could stand a few damage buffs because it's literally all she brings to the table.
Some work could also be done to improve her love tap gameplay. For example a speed or range increase when successfully switching love taps between champions would go far in supporting miss fortune's unique playstyle and strength of being better against multiple enemies
