Non-diminishing returns from armor-stacking would be true if you only faced physical damage. In reality stacking armor offers linear returns against an all-AD team and diminishing returns against any other mixed physical+magical team.

To use an example: Imagine you have 1000 heatlth and are hit by an enemy AD and afterwards by the enemy AP.

(I) The AD hits you first and, to use 100 Armor increments, leaves you you with the following amount of health based on your Armor:

100 Armor -> 500 health remaining

200 Armor -> 666 health remaining

300 Armor -> 750 health remaining

400 Armor -> 800 health remaining

(II) The enemy AP hits you straight afterwards and in order to kill you, they need to inflict the following extra damage, for each 100 Armor you had on you when the AD hit you:

100 Armor -> needs to inflict 500 magic damage to kill you

200 Armor -> needs to inflict an extra 166 (666-500)

300 Armor -> needs to inflict an extra 84

400 Armor -> needs to inflict an extra 50

So with every extra 100 Armor you bought the enemy mages needed to inflict less damage to kill you. Now if instead of Armor you had stacked health, each 100 health would increase your resilience by exactly the same amount as the next 100 health you bought. See the difference?

So, three random scenarios:

(a) Against an All-AD team, stacking Armor has linear returns.

(b) Against a mixed Physical-Magical team, stacking Armor has overall diminishing returns

(c) Against a team with predominently NON-Physical damage (ie lots of MAGICAL or TRUE damage), stacking Armor has increasingly diminishing returns

Considering that almost no games of League of Legends fall under scenario (a) I find that claiming Armor-stacking has no diminishing returns is misleading.
