Can we get a level locked upgrade for the normal vision ward?
Can we get an upgrade for it? Like level 9 or later unlock it to place 2 wards at a time instead of just one? That way its not as good as a sightstone not making that item invaluable but its better than the dark ages when everyone's one ward is on cd and there are no item slots left for pink wards

. Vision wards are a great counter to any champ using stealth and making it more accessible will require touch on stealthed champions too. Just wait for the upcoming season and the stealth rework and, who knows, something similar to what you suggest might be introduced.
