this build is pretty late game. and you need to poke as much as you can and farm. late game you have the overall balance. it is better than AP ezreal in late game. you can hit tanks pretty hard. and you can dual very easy with every kind of champ. except for zed. fck zed. xD. and the reason why you really only have one ad item is because that is all you need. by going high mana and double tear you get bonus damage for ap and ad and that is what ezreal needs. hextech gunblade is funny but you must not take it that often unless you really do need it.
