should all items scale off champion base stats?
the introduction of 
seems to introduce an interesting design concept. we have other items in the game that scale off the individual champions. most namely items that grant % base health regeneration and % base mana regeneration, and % attack speed. but this was the first instance of an item that grants a static attack damage bonus off a champions base ad.
the advantages of scaling items stats off the individual champions are obviously, that it allows for better tuning of the synergy between individual champions with an item.
no longer would a particular item have to be nerfed or removed because it synergizes too strong with a handful of champions, but instead riot could better tackle an overpowered or underpowered champion indivbidually by touching his base stats and therefor changing his synergy with every single one of his core items.
what would happen if there was no flat armor, mr, health, ad, mana, on items anymore, but only % increases off champion base stats?
the only exception to this would probably be stats like penetration, ability power, and critical strike.
