7. About Armor Penetration vs Damage runes.
It has been said for a long time that armor penetration runes are a must for Ezrael, it has been said that without them Ezreal will suck. Some people claimed (myself included) that some armor penetration + atk damage runes were better but what is actually true?
Thanks to some great research from Ryther, i do now have the answer, Ryther you are the man, i'd like it a lot of everyone who reads this and find this section useful to credit him in a comment!
Most players who argue that armor penetration is better is because it's better late game, and yes that is completely true, it is better in every aspect, but by how much? I have a very detailed calculation of all the different rune setups imaginable + a detalied calculation of every base armor stat for each champion.
To make this easier for me to explain, let's say we are using the same masteries i'm using, 21/9/0. If i were to go with armor penetration marks and quints and buy a doran's blade as my starting item, my damage on level 1 would then be 62 against an average champion if i were to go with 3 damage quints and 6 arm pen + 3 dmg marks i would end up with 72 damage against the same enemy champion.
Okay, i don't think anyone doubted that damage runes early game was better than armor penetration, but now that we got that settled, let's see when armor penetration get's better than damage and by how much.
I will display the difference in damage from level 1-18 with each setup of runes.
Armor penetration Quints and Marks:
Lv1=62, Lv2=65, Lv3=68, Lv4=71, Lv5=75, Lv6=76, Lv7=76, Lv8=77, Lv9=77, Lv10=77, Lv11=78, Lv12=78, Lv13=78, Lv14=79, Lv15=79, Lv16=79, Lv17=79, Lv18=80
Armor Penetration Marks and Damage Quints:
Lv1=72, Lv2=72, Lv3=73, Lv4=74, Lv5=75, Lv6=75, Lv7=75, Lv8=76, Lv9=76, Lv10=77, Lv11=77, Lv12=77, Lv13=78, Lv14=78, Lv15=78, Lv16=78, Lv17=79, Lv18=79.
As you can see, going with armor penetration quints and marks gives you better damage at level 6 but it's not even by 1 damage, and even at level 18 the difference is also less than 1 damage. And if you look at the damage early game you get much more damage early game with the damage quints.
UPDATE!
I've received A LOT of questions regarding this matter, and A LOT of players are not convinced at all that damage runes could be even slightly viable on any champion, i think what most players are forgetting is that first of all armor penetration runes were nerfed and that they really have no idea how much the extra armor penetration will help you mid/late game. So therefor let me give you an example of how "good" the armor penetration runes are mid/late game.
Because of the fact that the more damage you get the more damage you will deal with your armor penetration runes, and this is what confuses a lot of players. So for this example let's say it is mid game and i'm level 13 i'm using full armor penetration from runes and masteries that would give me 31 armor penetration. For this example i have 250 atk damage.
Now let's say i am attacking an enemy with 100 armor.
Target armor: 100 - 31 arm pen = 69
Damage reduction = 69 / 169 = 40.8%
My actual damage to the target = 59.2% of my total atk damage.
250 x 0.592 = 148 damage
Now using my setup i would have 16 armor penetration from runes and masteries and because i have 10 atk damage from runes i would then have 260 total attack damage with the same items at that point and time in the game.
Target armor: 100 - 16 arm pen = 84
Damage reduction = 84 / 184 = 45.6
My actual damage to the target = 54.4% of my total atk damage.
260 x 0.544 = 142 damage
[color=yellow]
Now it is up to you to decide, would you rather pick 10 more attack damage by the time your enemy has about 500hp or would you rather pick 6 more damage by the time your enemy has about 2k hp? I think the answer is very simple.
There you have it folks, now please don't ever ask me again why i pick damage runes instead of armor penetration
