Thornmail always did the dmg pre mitigation and it's still 15% pre mitigation dmg. The thing with new Thornmail is that it buffs his ratio from W to 10% armor + 25% bonus armor. Now it synergyse even more with rammus kit and recomends him to stack armor.

On the other hand Thornmail was nerfed for not armor stacking targets, so it's pushing the niche of Malph and Rammus.
