@BranePowerGuy If you do understand how it works and were just using the wrong term (using the term AP when you should have said magic damage), then you should also understand why it's not very good at all against mages (in you're example, Akali). Only 30% of the PHYSICAL damage dealt by Akali's auto attacks were reflected back. Akali generally builds AP, which she uses to do her damage through her spells. Yasuo on the other hand, builds AD, and uses a plenty of autos (not as many as a ADC, but still quite a few) and has a fair amount of damage sent back at him by this item. You do have to remember that none of the damage from his Qs or other spells are being reflected, so he could theoretically work around this item by just using spells on you. Generally speaking, the thornmail is a bad item on Heimer, as his kit benefits a lot from building AP to deal damage (Remember this is not the same as the magic damage that thornmail reflects). Heimer doesn't build defensive items bc he wants to as much damage as possible, and relies on teamates and his turrets to keep him safe in lane and teamfights.
