On-hits trigger Thornmail's passive. Itemizing against a late game Fiora is kind of like itemizing against a Vayne; it's pretty difficult.

Some champions do so much damage that they just override Thornmail i.e. Yasuo, Nasus, Tryndamere. And what if they build magic resist, like Spirit Visage, then Thornmail doesn't even negate the lifesteal.
