And in doing so you have no idea if the ward has been replaced or not. I see and understand your point, but it only takes into account a minuscule amount of the possibilities. You can go ahead and ghost a match for a friend, telling him when and where wards are placed (and because of the delay, expired) but you might be leading him into a fresh ward without knowing it.

Generally speaking, bot and top lane will always be warded. Ward are replaced when they run out. Fewer mids ward, but it is still likely to happen.

TL;DR: If you're watching a match that's actually worth ghosting, your information will be near useless.
