Can Taliyah's passive actually be useful?
Taliyah's passive has no impact on her whatsoever, she gains movement speed when she moves next to walls, but she rarely needs it, it doesn't really help her get away, because if she's attacked, it stops it. And she can't jungle, so it doesn't help her much there, and when you roam as Taliyah, most of the time you can just wall in. If you're going to give her a movement speed boost, at least make it she doesn't always have to be next to walls for it to activate.
Honestly, if you change her passive completely instead of buffing her Q ALL the time to try to fix her low win rate, it would probably make her a little more balanced.
. I don't see a problem. Nope, not at all.
