Melee AD's are confined to one of the solo lanes or the jungle. They're also seldom played because they have all the weaknesses of a ranged carry (squishy, shut down by attackspeed slows, extremely item dependent, etc.), but none of the key advantages (range). Even if he were to include a section, it would be nearly identical to toplane.
