I'm not sure anyone would build Thornmail to counter an AP. But here's the thing: normally you'd buy Thornmail if the enemy team has something as AA-heavy as a Tryndamere top, a Draven ADC and an Udyr jungle. But if there's a Kayle mid and a Thresh support, well, Thornmail suddenly becomes a must. Consider that, since now the damage scales on bonus armor, the item is more of a tank-specific item. Tanks will always have a MR item before thinking about Thornmail.
