Name some old abilities or old kit numbers a champion had that made them pretty OP
Old W, wayyyyyy back in the day use to burn the enemies mana on hit.
Old E scaling use to be 300 base damage + 1.0 AP at max rank., this didn't last too long, the stacks for it was also only 4 at some point on top of that.
Old Q scaling use to be 280 base damage + 1.0AP at max rank, the base damage stayed pretty long, but the scaling was reduced soon after he was released if memory serves right


Essence Flux used to not only give an enemy AS debuff, it originally healed every ally it hit.
passive used to give 2 HP per AP and 1 AP per 25 Hp
His Q used to have a 3 seconds CD at max ranks which means 1.8 CD with 40% CDR.
