@Meddler: What would be required to allow Rammus' ultimate to scale off his armor?
Rammus' Tremors is somewhat bland in that it doesn't scale with our Armordillo's chief stat: Armor. It instead scales with AP, which Rammus (almost) never gets outside of Baron buff. Pretty lame.
I'm sure the thought of making Tremors scale instead with armor has crossed Riot's minds, but so far it hasn't been acted upon. Why? Would it make him super OP? If so, what would be necessary to make armor scaling balanced on Tremors?
