If you look up tanks he doesnt have a link on the wiki even though he's still labeled as one there.

He is called a melee fighter here but i'm pretty sure he was called a tank once.

He keeps getting nerfed alot and the nerfs always seem to make tanking harder.

yes, i am aware that the champion type is not based on a label somewhere.. but months worth of future game balancing are.

Not necessarily, but since most people are building him full ap now, he is more squishier that before, but he is still classified as a tank, and he is so awesome!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
