She feels a little too weak...
At least for mid. I don't play her support (though she was pitched as a mid laner).
In extended fights, I guess she's OK. But her kill potential seems a bit too low. Given that keeping her passive on someone is already a feat, she doesn't really contend with anyone imo.
She definitely needed a nerf, but I think they went a bit too hard. Or at least extend the duration of the passive so you can actually stack it up.
I'm not really feeling the synergy in her kit anymore.
