Regarding Raptor's Smite Bonus

It would be nice if the bonus effect from smiting the Crimson Raptor didn't proc on a ward that is already visible to me (a friendly reveals an enemy or an enemy is revealed by a friendly ).

I know that this ward exists, and I would like to clear it. However, If I choose to clear said ward that I already know can spot me, I waste my smite bonus.

If I want to keep my smite bonus to find an enemy ward that I cannot actually see, I have to avoid the radius of the enemy ward, which allows the enemy to maintain vision control in that area and could potentially limit my ganking options.
