Riot you've got to nerf AD if you ever want to change the game
As it stands the stat itself is far too powerful with too much diversity in the champions that use it, and until you nerf how much it scales, it will always be required that you have at least one auto attack carry on your team, if not more, because trying to make any AP champion scale better will be impossible and trying to make any melee AD champion be able to withstand such an obscene amount of damage from a possible ranged opponent will make them blatantly more powerful than any melee opponent who wasn't given the same defensive capabilities.
The only way you could get around that would be to give them burst damage to not need the defense, in which case you're just talking about AD assassins like zed or talon.
