IE has poor cost efficiency compared to PD and BT, its main purpose to make crit you has much stronger, wich makes no sense rushing it. The reason why ppl like to rush it is because you get both good crit and AD wich combined with AS from zerks gives balanced DPS despite low cost efficiency. Thats the thing, you can buy BT/PD for insane amounts of stats you cant use or you can get IE for mediocre amount of stats you can use very well. Champs like Graves who has decent AD ratios favors BT, champs with AS scaling and AD steroid can start with PD(Vayne) but champs who got nothing(Ashe) has to either go IE or mix components.
