Uhhh.. armor?
It's thing
Armor or MR doesn't mean anything if you don't have health backing it up. Even a pure armor Rammus 80-120 health isn't helping him any. Even if an ADC's damage is reduced by say 80%, and that is being generous since reduction % gets lower the more you stack. That will cut off 640 damage off a 800 crit, so they still will hit you for 160, so that is 1 more auto to kill him. But this is not taking into consideration that 80% reduction isn't happening, the ADC most likely getting Armor Pen and basically ruining everything he worked for.
destroys Rammus since effectively half of all his armor is completely ignored, on top of you dealing %extra damage to him.
Let's use the 80% reduction again, that 800 hit will now only mitigate 280 damage due to the armor pen, bringing it to 520 damage, assuming the %extra damage is applied after, add in another 78 and you are basically hitting 600s on him, that 120 health isn't saving him from being killed in roughly 6 hits which for an ADC is basically 4 seconds.
Basically the point I am saying is even with insane Armor or MR, 100 health isn't saving anyone. You are literally better off using Undying if you are a tankier person since it outright deals 4% max hp damage and heals you for it. With 3k hp which anyone can easily get, (tanks can actually get to 4-5k) you are basically hitting 150 free extra damage every couple seconds that also is giving that damage to your health. So literally 1 hit is already better than that extra health.
(Numbers I am sure aren't 100% correct since it is bonus armor and I don't know how to equations work, but its a rough estimates)
