"Armor does not have diminishing returns. Every point of armor adds 1% EHP to your champion."

Whoever wrote that on the wiki has a very strange concept of "diminishing returns".

I get more benefit out of 25 armor (per point of armor) than I do out of 400 armor. Specifically,16 times the armor, for 4 times the equivalent benefit.

16 =/= 4, Ergo, diminishing returns.

This relationship can be proven using any non-zero base (since anything times zero is, well, zero). Hell, just plotting the armor function alone would show how even with infinite armor, you would approach 0% damage, but never reach it, and asymptotes are obvious indicators of non-linear behavior.

And non-linear behavior indicates that the value of armor isn't constant; but varies (if you took the derivative at any point along that curve, it would be different; mathematical proof that the gains are diminishing, albeit cumulative)
