To your extreme example, the one who started with 0 armor penetration will gain more out of the 50% armor penetration. He reduces 500 million armor which reduces the enemy effective health by 500 million percent, while the other one would decrease it by 50 million. Huge difference.

''We only care about Armor/MR to the extent that it reduces our damage. If diminishing returns on %reduction doesn't result in diminished damage increases, it is non-synergistic?''

That is a huge misconception. % reduction/pen does not directly increases your damage. It's method is by reducing the effectiveness of armor. Therefore, % reduction/pen is a dependent stat on armor, which just happens reduces damage at a decreasing rate of increasing. Though one may be able to conclude that % reduction/pen increases damage, there is no direct correlation between those state with increase damage.

Therefore, the fact that your damage is increases doesn't change the fact that the actual effectiveness of removing/ignoring armor is decreasing with the more acquired of those stats, which is what that stat does.

And that's where this misconception comes from is because you're making jumps from one stat to another that are loosely related.

''Actually that's exactly what Armor does. It reduces incoming physical damage by a percentage. "Effective health" is nothing more than a handy way of explaining why Armor doesn't have diminishing returns.''

And the only way % reduction/pen can have a synergy is by using the math wrong and having the need of the constantly decreasing rate of increase in damage reduction.

That's the only reason why your math comes out half decently, it depends all many different situations with other variables to work it out. With the slightest tweak to the numbers, you would

And for your math, how does: (new reduction/old reduction = increase boost) even make sense when they don't have a linear progression. Your finding the percentage difference but yet there is a exponential rate of increase the bigger the difference.
