Make ward silhouettes appear as "default wards" when sweeping them out of vision
I swear half the time if there's a small champ in the game I freak out for a second thinking that's them in there only for it to be some type of ward.
I think the best examples are the Pulsefire wards (original and 2018). They're way bigger than a normal ward and just look like giant indiscernible objects when swept.
