There are a lot of champions that can melt you away is less then a second, plus there are items that cut through armor. Upgraded Armor items are long past due. Please stop nerfing the lil armor we do have in the game and make armor items more competitive.
If you think armor itemisation is bad then just look at MR. All the MR tank items have been nerfed into uselessness. Spirit Visage is OK if you can abuse the increased healing and Adaptive Helm is ~ok against champions like Ryze or Cassio. But even then 55 MR, 350 health, and 10% CDR isn't amazing for 2800 gold.
You can buy a kindlegem for 800, ruby for 400, and then a negatron cloak + null-magic mantle for 720 and 450 respectively. That's 2370 gold for 350 health, 65MR which is 10 more than Adaptive Helm, Spirit Visage, or Abyssal mask, and 10% CDR. Of course, that's not slot-efficient but completed MR items are just total trash, way too much of their cost just goes towards passives which you might not even be able to utilise.
What are you talking about? You buy ninja tabi and become invincible to any champ who doesn't use Conqueror
