Janna nerfs amuse me you know why?

Doesn't matter how many times you nerf her.

She'll still be the best support in the game. lol There's nothing that competes with a good janna, Nothing. Good janna with Q your Gap closer. Good janna E ally then tanks the first spell you cast on her adc. Good janna pops her R to blow your tank/apc off her back line while her tanks run into your back line with sherlias Doesn't matter how many nerfs you give her riot. her kit is the best kit in the game for a support.

So stop trying and just accept it ;]
