I have to say I find AD by far the hardest lane to really outplay your opponent. On "my level" I sometimes win my lane pretty hard, but not as hard as I can top/mid. Say in the last 20 games I played, I had quite a few in top or mid where I could eventually tower dive my opponents and kill them 1v1 (Diana, Singed, Jayce) because I won my lane so hard. In botlane, if I win, it's a lot harder to emphasize. If you push your tower you can roam a bit, maybe take mid turret, but because of the support it's a lot harder to steam roll your gold, especially since AD's are generally quite underpowered early/mid game. You need 2 items before you start doing noticable damage to a tank or bruiser. This is more the case for a Caitlyn than a Varus or Kog of course. Or when you play like Leona/Blitz with Draven, but that rarely happens.
