that is a valid reason, but at the same time AP is a lot more gold efficient, i mean its easier to stack 800AP than say stacking 500 total AD.

on the other hand the reason why stacking raw AD is highly cost inefficient is because most AD items are coupled with other stats that boosts their overall cost up.
