Thornmail isn't as useful unless youre stacking armor
thats exactly the problem. they made it stupidly binary.
it only really does anything now if you have a ridiculous armor steroid. malphite, rammus, maybe taric. it starts getting noticable at about 400 to 500 armor. if you can get to 700 armor with malphite and a thornmail, adc start killing themselves on it unless they have mercurial.
last season after the change i managed to get 780 armor on malphite total. with 10% damage reduction from tabi, 10% crit damage reduction from randuins, and another 10% crit damage reduction from masteries.
this was mainly possible due to adaptive armor, and 10% bonus resistances from masteries. so even with a pure armor build i had enough mr to survive mages.
that was about the point i could 1v1 vayne.... before her buff.
well, most of the masteries that made thornmail strong, even on malphite are also gone or nerfed now.
so basically on every normal tank or fighter who gets up to 250 to 300 armor, thornmail is pretty much entirely useless.
