Honestly, if I had to say a reason she needs a rework is because she's doesn't really fit the tank role. Her kit, to me, feels more like a bruiser ala Mundo than a tank ala Amumu/Rammus.

Sure, she's got a powerful slow and a AoE stun, but her main value in a fight is damage. She does quite a bit of it, and you could say her massive burst slow and AoE stun is enough, but it never felt right to me.

She inhabits kind of a weird place with Volibear where they aren't 'quite' tanks, but there's no better catagory to put them in.
