So when do you nerf mid Karma?

I played as Xerath, I landed 90% of Qs on her, but every single time a spell hit her she would shield and I would deal 0 damage. I supposed she was maxing her shield, because if a rank 1 shield could nullify a rank 3 or 4 Q then that would be bullshit, but also because she didn't land a single normal Q on me to see what damage she deals. But even then it didn't matter what she was maxing, because she would just pop ult, miss her empowered Q completely and still somehow take 1/3 of my HP with it with less AP than me. What the %%%% Riot?
