Hey, I need a number cruncher dude to halp a bro out. Would it be better to run either pure flat AD/AP runes as opposed to running a mix of flat AD/AP with their respective penetration?

Depends on what champion you're playing, what team composition your pals are running, and who the competition is.

I'm uncertain at this point as to which way is generally better, but I can say that if you're running an assassin/burst champion with a dominant early game, penetration marks would probably be better.

As for formulas, here's damage after mitigation:

Code:

(Full Damage) * (mitigation factor)
Mitigation factor = [100/(100+defense)]
where defense is either Armor or Magic Resistance.

100 Armor = 50% physical damage received
200 Armor = 33.33% physical damage received
300 Armor = 25% physical damage received
etc.

Effective HP = HP/(mitigation factor)

Assuming 2000 HP:
100 Armor = 4000 EHP
200 Armor = 6000 EHP
300 Armor = 8000 EHP
etc.

At first, it looks like there's diminishing returns, but if you calculate it in another way -- effective HP -- you'll see that every single point of defense is worth the same. The concept of EHP is that instead of calculating how much damage a champion can take in mitigated form, you can instead calculate how many attacks it takes to kill that champion by just adding up the damage being dealt, rather than received.

Realistically speaking though, the first 50-100 points of defense is worth more however, since without those defense stats, you're well within the range of getting bursted down by a gang of champions and not being able to do a single thing about it if they get the jump on you. Hell, 5 champions unloading everything on a champion with 200 defense and 2.5k HP is still likely to kill, although then his teammates can just retaliate with impunity. Being alive and being dead are two very different things.

True Damage always does full value, and can never be mitigated or increased (although shields absorbing damage and Kayle's R is a different matter).
