Actually, that's an example of counterplay that Riot does not like because it isn't meaningful - it's binary. You buy a vision ward and they are countered; the ward is visible because it was overpowered when it wasn't, but now your ward is dead and suddenly you're completely vulnerable. This is not engaging - it's hoping they don't notice your ward but still walk past it.
