Wards need a new touch up

With the addition of Kayn, wards are now in need of a buff. As of now, they only show vision in an area up to an obstacle (IE: wall). However, now we have a champion who can sit inside walls, out of the vision of wards that are right next to him. And unlike other champions who go through walls, Kayn has the uncanny ability to chose where his exit point will be. Wards are unfortunately outdated now. We need more vision into walls, even if it's only half the effectiveness.
