Ok, because the search function is down, i am unable to find a solid example on the effectiveness of Armor penetration, critical and attack speed. therefore i decided to do a little maths craft myself.
bear in mind that as you read this, there are certain mathematical rule i would need to bend.

Critical chance comparison with Armor penetration where AP=armor penetration AS= attack speed CC= critical chance A= armor (where A - AP cannot reach less then 0) D= damage and ?/0 = 0 (yea. bending the rules here) CC= 100AP / (100 + A - AP) i will explain how i get this later using example, assuming A= 100 and AP= 50, you will get CC=33 meaning you will need 33% critical chance in order to reach the same efficiency as 50 armor pen over 100 armor using example, assuming A= 500 and AP=50, you will get CC= 9.090909... meaning you will only need 9.09% critical chance in order to reach the same efficiency as 50 Armor pen over 500 armor using example, assuming A= 100 and AP = 80, you will get CC= 66.66.. meaning you will need 66.67% critical chance in order to reach the same efficiency as 80 armor pen over 100 armor Raw formula assuming Armor pen. Critical Chance 100 / (100 + A - AP) * D * AS = 100 / (100 + A) *CC *D *AS |
after some formula revision, i realize that Critical chance can be as good as Armor penetration in the early armor level (1~100) before you mind is blow away by the complexity of the formula. i shall simplify things. if (100+ armor)/ 2 = AP then you will need max critical in order to reach the same efficiency. sorry for the wrong first formula

Attack speed and damage has a rather complicated way of understanding. (multiplicative) as you stack AS and D, the more you stack, the lesser efficiency you get as you stack. this is the diminishing return rule. e.g. 100 damage + 100 damage = 100% bonus 200 damage + 100 damage = 50% bonus 300 damage + 100 damage = 33% bonus the same goes for attack speed as well HOWEVER this only apply if your comparing to previous DPS (additive) if you look at base DPS, stacking AS and D is additive. Therefore 100 base Damage + 100 Damage = 100% bonus 100 base Damage + 200 Damage = 200% bonus etc etc BUT its important to remember that 1 base Damage + 100 damage = 10000% bonus 1 base damage + 100% attack speed = 100% bonus 150 base damage + 100 damage = 67% bonus 150 base damage + 100% attack speed = 100% bonus |
as base damage gets higher, the return of getting more damage is reduced as compared to attack speed.
before you quote one of my sentence to flame, please read finish first
QQ.
1)but the price of 1 damage is different from 1% attack speed correct? so its wrong to compare them this way
yes I'm well aware of that, therefore for the sake of connivence, i would just assume that the value of Critical chance, Armor penetration, Damage and attack speed is the same.
2) why is your DPS formula so short? what happened to Critical damage increase?
for the sake of simplicity, i got lazy :P sorry bout that. but yea. Crt damage does increase your damage.
because its difficult to place a price on any in-game items, i would use IP instead,
AD = 227IP / damage
AS = 241IP/ attack speed
AP = 209IP / armor pen
CC = 440IP/ critical chance.
with that being said, it would seem in terms of numeric value, armor pen wins
which stats being more advance effective would be base on you readers. ultimately there are so many factors that affect DPs. how would you build you hero?
the full formula of DPS would be
Attack speed * Damage * ( 1 + Critical chance( 1 + Critical damage / 100 ) / 100 ) + special damage modifier = DPS
DPS * Armor / (100 + Armor - Armor pen ) = output (i'm being easy on the armor pen and reduction.)

1% CC will increase your DPS by between 1% and 0.5% if you have between 0 and 100% CC, but increasing CritDmg slightly improves that DPS increase. 1% AS will increase your DPS by (1 / (1 + AS)) until you reach 2.5 attacks per second. 1 Damage will increase your DPS by (1 / D). 40% ArmPen will increase your DPS by a wildly variable amount. If they have no armor, it will not increase your damage at all, if they have infinite armor, it will increase your damage by 66.7%. If they have 200 armor, it will increase your damage by 36.4%. If they have 100 armor, it will increase your damage by 25%. Remember that percentage armor penetration is applied AFTER flat armor penetration now, so they stack fairly poorly. |
EDIT
correct a basic formula error (thanks EnderA)
Added in more facts thanks to EnderA
