Just some math I did to discredit another thread about Armor becoming obsolete:

I thought this might be interesting. Although it only applies to one scenario, so beware that. Edit: This is only to show Armor Penetration isn't becoming stronger. It can well be that Tanks are still being killed more easily than before, I don't know.

Last Whisper is a UNIQUE Passive:

  • 40% BONUS Armor Pen from a Last Whisper item
  • 10 from Maw of Malmortius
  • 20 from Youmuu's
  • up to 30% Armor DECREASE from Black Cleaver
  • 7% TOTAL Armor Pen from Masteries
  • X from Runes

Riven, I assume, would buy all of this. Let's take a Tank with 90 base Armor and 210 bonus Armor (300 total):

  • Black Cleaver reduces armor to 210 (63 base + 147 bonus)
  • Pen 14,7 from Masteries
  • Pen 30 from Items
  • Pen 58.8 from Last Whisper
  • Total: 103.5 Pen
  • 210 -- 103.5 = 106.5 Armor against Riven after she has applied all Black Cleaver stacks
  • This reduces her damage by 51.6%

##And now?

  • 35% total Armor Pen from Last Whisper
  • +4% from Masteries
  • 20 from Youmuu's
  • up to 30% Armor DECREASE from Black Cleaver
  • X from Runes

Tank has 300 Armor, base and bonus are irrelevant

  • Black Cleaver reduces Armor to 210
  • Pen 20 from Youmuu's
  • Pen 117 from 39% Armor Pen
  • 210 - 137 = 73 Armor against Riven after she has applied all Black Cleaver stacks

#ERMAHGAWD Riven does more damage NOW !

##Let's try this on Marksmen, shall we?

Marksman has 91 Armor (82 base and 9 bonus):

  • Black Cleaver reduces armor to 63.7 (57.4 base + 6.3 bonus)
  • Pen 4.46 from Masteries
  • Pen 30 from Items
  • Pen 2.52 from Last Whisper
  • Total: 36.98 Pen
  • 63.7 -- 36.98 = 26.72 Armor against Riven after she has applied all Black Cleaver stacks
  • This reduces her damage by 21%

##And Now?

  • Black Cleaver reduces Armor to 63.7
  • Pen 20 from Youmuu's
  • Pen 28.84 from 39% Armor Pen
  • 63.7 -- 48.84 = 14.16 Armor against Riven after she has applied all Black Cleaver stacks

#Conclusion: This is at the very least a nerf against late game damage dealers. So flame about that instead of just assuming everything is OP.

% penetration is applied before flat penetration.

But it doesn't actually change anything about the end result here, does it? I'm confused and worried I might have made a mistake, please elaborate.

it does. if you take away 20 from 100 you got 80. 30% from 80 = 24 -> 56 left. 30% from 100 = 30. take 20 away and you are at 50.

I assumed it went like this: 100 - 30% = 70 (% Armor Decrease) 70 x 35% = 24.5 (% Armor Pen) Total Armor Pen against this target = 24.5 + Armor Pen stat (Flat Pen)

I have also a calculation. It compares the new Last Whisper with the old one if it gets bought by a Zed who fights an Ahri with Zhonias. I will post my calculation later if you want.

Lies, damned lies and statistics.

Have you played on the PBE? Tanks just melt.

But not because of Armor Penetration being too strong, it's the other factors they've implemented that cause this (like SOO much Crit Chance, insane Life Steal, CDR, Attack Speed and Range increases, on-hit damage on every other item, Movement Speed, Damage Reduction on Marksmen, so they don't die so fast, etc. etc. etc.)

Edit: And, of course, the Marksman kit buffs.
Edit 2: (There's just so much, isn't there?) And the Keystone Masteries, which offer other avenues of damage. I heard that the Thunderlord's Decree (?) Mastery deals 180 damage on its own at level 18, without any AP or AD. With, it must deal so much more damage, and we all know Tanks just hate AoE damage.

Do at least be honest with yourself and include the 15% damage increase because lol fuck tanks.

This doesn't take into account other changes. You are trying to exclusively look at one variable without the impact of others. Hell you even agree on that but you argue that tanks are not getting hit hard?

Illâoi Evê Siôn1 votes

I did not argue that. I tried to clarify myself in an Edit a minute ago. Please read it ^^
