Lich Bane scales, though. Working with your example of a champ with 110 AD, Lich Bane breaks even at 275 AP (137.5 damage + 82.5 = 220). You can achieve this by your 3'rd item quite easily (Athene's + Luden's + Lich Bane, a common build for Fizz, for example). After this point, any more AP you get will only help LB further surpass Tri Force. Also, as was mentioned, Magic Damage tends to scale better into late game, because champions have lower base MR than Armor (especially ranged champs, who don't have scaling MR), and the itemization for MR isn't as strong as Armor items (Thornmail & Frozen Heart, both super cheap 100 Armor items, vs Banshee's & Visage both clocking in at 55 MR for a higher price).
