How do these really affect dmg? I always thought these give you additional dmg when an enemy has armor and MR. But now since I read some guides and saying these help early game, why not AP/ AD runes instead?

Every champ starts the game with a small ammount of armor and magic resist. Penetrating runes could negate most or all of that defense. If so, then your attacks and spells will do true damage early game.

1 point of armor/magic resistances increases the amount of physical/magical damage required to kill a champion by 1% (if this surprises you, look for effective health).
So 1 point of ArPen/MrPen decreases the damage you need to kill the target by 1% (unless its armor/MR its lower, it cant be negative)
