If armor doesn't get buffed along with Marksmen buffs/item changes I will be very disappointed
I still find no reason at all for the Armor item nerfs other than to tone down how strong bruisers and juggernauts are. They are the problem with their great stats and ability to tank massive damage and deal massive damage, usually with a sustain mechanic too. As for tanks a ton of them have been nerfed through out season five directly and indirectly, many reworked champions have strong anti tank abilities or passives (true damage,armor pen/shred/ignored, %hp damage, etc), and basically all tank items nerfed heavily.
It has been hard enough to survive the threats in top lane as almost all of them use
and Armor is just too expensive and proves to be irreverent as you struggle to buy that one armor item your opponent is already buying more offensive items/shredding tools. Armor was kept cheap so it actually made a difference, it was strong but shredding options along with your ADC a great amount of damage was the way to deal with a tank with armor. We will be in very dark times if Marksmen become kings of league and deal even more damage then they deal now and armor is still left nerfed to the ground like this.
