Armour can kill

So today i decided to look at the possibilities of Armour after seeing a Malphite with 606 Armour in my game last night. Here is what i found:

Malphite can be damn scary as he can reach 1 386.77 ~ 1 389 Armour or 93.2% resist 1 - 100 / (100 + 1 389) permanently instead of 1k+ temporarily with old w.

How is this obtained?

You would need a Taric and Braum. All 3 must build 6 thornmails and be running Enchanted Armour, Hardiness and Legendary Guardian as well as Greater Mark of Armour x9, Greater Seal of Scaling Armour x9, Greater Glyph of Armour x9 and Greater Quint of Scaling Armour x3.

This allows for all 3 champs to gain : 62 Arm - Runes 5 Arm - Mastery 20 Arm when near 5 enemys - Mastery 5% Bonus Arm - Mastery

Now the calculations for Taric and Braum must be done -

Taric 6 Thornmails - 600 80.3 base @18 30 extra form w passive 62 from runes 25 from mast 5% from mast

That puts Taric at 837.16 Arm Thus his w would give 100.45 Arm to others, 12% of his.

Braum

W - 25 + 16% bonus armor

6 Thornmails - 600 62 from runes 25 from mast 5% from mast 100 from Taric

W would give 136.4 Arm when used.

Now for Malphite

92 base 6 Thornmails - 600 62 from runes 25 from mast 5% from mast 100 from Taric 136 from Braum 30% from passive

This means Malphite can have 1 386 Arm This means his w would do 636 before mr.

This would never work due to diminishing returns but its odd to see our favorite rock can have over 1k Arm.

Now I also decided to look at Rammus and found he can actually kill you quite easily, if he manages to live with 2k hp.

Rammus

96 base 6 Thornmails - 600 62 from runes 25 from mast 5% from mast 100 from Taric 136 from Braum 120 from w

Rammus can have 1 145 Arm. This means he gains an extra 286 AD form his passive giving him 401 AD at 18. If i were a ADC id be afraid of 401 ad and 91% reduction.

Now lets look at the other part of w, Rammus deals 55 + 10% of arm dmg when attacked.

This means he would deal 169 + 30% dmg every hit.

If a ADC were to hit Rammus for 300 as Thornmail looks at dmg pre resist they would take 169 + 30% aka 259 or 86% of damage delt.

300 damage for a adc is standard for a full build late game.

Rammus new non viable adc counter?
