Some of those were baselines for the loss of scaling hp runes and mr, every midlaner ever got that. Not only that, but one of those was a revert to her base hp scaling being nerfed in prep for proplay, so basically.....nothing really was done aside from a scaling cd mechanic on her passsive and a 5% ap scaling. And that all(I say it like it's even a lot) took place in a span of almost two years.
I'm so sorry if I'm sounding rude or anything here, it's just we've been getting told that they'd look into a passive for her, for nearly 3 years straight. When they finally find something, they show it us and then delay it more because it didn't "fit her". The Liss community has posted a plethora of passive ideas or general just stuff that could be done outside of base stat buffs that could actually make her viable, for again, nearly 3 years. It gets really frustrating.
Now I'm not saying we should fucking I don't know, riot(heh) with pitchforks and torches, but I would not be surprised if Meddler said the current tentative passive change is going to be shelved when 8.8 gets here.
