AD will still be stronger early in the game and Crit Damage will only do something, if you already have crit chance:

Formular: AD * 1.1 (basic value) + AD * critchance * (1+critdamage)

When you have no critchance, Crit damage runes will do nothing for you. Crit damage runes are more then double potent then crit chance runes(only from the raw value), but you normaly increase you crit chance by arround 50% through items, and your crit dmg by 50% with IF. Crit chance will be multiplyed by 1.50% and crit damage by 50% so crit chance is still more potent then crit damage.

The thing is, why would you stack you runes full for a small lategame benefit, when you increase your early game with raw AD + AS. Better lasthitting and trading helps to go through the early phases of the game and become a lategame powerhouse.
