Simply put, no other item in the game has 20 flat armor pen. Armor pen synergizes extremely well with AD casters as a means to augment strong base physical damage on abilities. Additionally, because there is an AS and Crit Chance component to the Ghostblade, said ADC will not be losing out on AA stats which are necessary for even caster ADCs.
