Ehp is an illusion, 1 armor at 50 armor decreae the damage you would take by 0.66%, while 1 ad would increase the damage you would deal by 2% and it also scales with AS and crit.

We also know stacking armor is even worse in s3.

If there was a flat damage decrease scaling with armor, 15% of armor before damage calculation, not a big deal for non tanks, around 4 damage late game, but about 10 for tanks, which is a decent buff and not over board op.
