So how about an item for AD Caster-types?

You know, the sort that aren't tanky.

( ) Grants AD, IAS, armor pen, CDR, and UNIQUE active: You may bind this item to one of your skills. Hitting an enemy champion or epic monster with a basic attack applies all damage and secondary effects from this skill to them, placing it on cooldown.

As it stands, AD Caster-type Marksmen often times end up reducing their DPS come late game if they use their skills. That just strikes me as silly. So the goal of this item is to allow them to incorporate the damage from their skills into their basic attacks without slowing down the pew pew.

It goes without saying that itemization for AD Casters is woefully inadequate, barring tanky derps like Garen and friends. An item like this would help to fill in the gap without making the more Assassin-y AD casters over the top. Typically they aren't terribly keen on attack speed and so this whole issue with pausing to use skills between autos typically doesn't bother them.
