Maybe completely rework Janna?
I mean seriously: every time I see her name listed on a patch note I know she gets nerfed. Still, she always benefits of meta changes and gets more nerfs.
That's the definition of a not ok kit. I wonder how her mains (if any left) feel every time she gets nerfed. I wouldn't be able to play this champ knowing she gets random nerfs every 3+ patches.
