She'll be fine once they figure out that she needs sustain early to survive midlane, if they remove it she will only be played toplane. Idc if she heals off her Q or not, attach it to her passive like before, but they shouldn't just remove her heal altogether.
I don't want her reverted, even though I loved the old Akali, this Akali is definitely healthier, she was mainly just disliked due her obscure mechanic. Once they remove it and buff some numbers she'll be in a pretty balanced state.
Don't remove the heal, Riot. Move it to another ability or something but she needs some form of sustain.
