Because you do not forgoe armor because your opponent has armor pen. NOT having Thornmail with his armor pen is worse than having it. If a Xin is tossing on armor pen, then Thornmail AND Rrozen Heart are the answer, or Randuin's. But, not only does Thornmail return damage it is the highest Armor providing item in the game. Black Cleaver is more of a reason to get thornmail against Xin then less, However if you are a tankey bruiser that can dish out a respectable amount of DPS yourself. . you probably only need the Thornmail.
