They need to rework her and choose which direction they want to go with her assassin or fighter. But for now, i would suggest giving her small mana buffs, lower her E cd or give her some kind of small As steroid on her E whenever she cc's them to make it more interactive with E and passive. Her kit is problematic but riot are too lazy addressing one moment they say she's a fighter designed in the jungle, but she has not enough fighting attributes neither does she have enough assassin attributes, so she's stuck in this weird spot where they cant buff her because she's oppressive. In a rework i would revolve her around her moonlight and make her passive interact with her kit more, right now her passive is just used for dps and nothing else, but they gave her that passive so she could kill jungle camps effectively but she's nonexistent there and even struggles in midlane with around 1-2% playrate :/
