Honestly, the problem is that armor does have diminishing returns. As does health, and attack damage, and ability power, and everything else that stacks additively. If you have an item that gives you +10 to a stat, that's great when you have 50 in that stat, but if you just keep adding and adding to the stat, the +10 becomes less and less effective. You see it in-game all the time: a has a prominent effect when you have 50 AD, but it's pointless by the time the end-game rolls around. That's a diminishing return. That's how arithmetic progressions work.
