Yeah, no. That's a fucking placebo nerf. She needs much, much harder nerfs than that. That's a little lovetap.
The ratio on her W needs to go down, and % damage on her passive needs to go down. She's already got god tier autos thanks to the bullshit items ADCs have, so her abilities don't need to do 800+ damage each.
And it's easy to tell if a champ is too strong, too weak or just right. But balance doesn't make money in an F2P game, especially when new stuff is involved, so we'll just ignore everything and let champs warp the game for months on end to make some money off of them.
