Im not saying anything about other laners, I am just saying that using vision score to grade players is bad.
Nearly every ward is useful, but only wards that see enemies count.
It's probably to prevent people padding their Vision scores by spamming pointless wards in their base, thus making them look better. They could fix this in many other ways, but their current solution seemed to be the simplest fix.
