What if pink ward gives exp. every time someone places it down?

I know that players especially in the lower elos don't use pink ward as often as pro players or challengers. So what if we give some sort of "reward" for buying and placing down a pink ward? Lets say that every time you place a pink ward you get some exp. This will help promote the usage of pink wards more and will give low elo players a reason beside vision to use their pink ward. In lower elos players don't buy pink wards because they feel like vision isn't that important to them. If you also get exp for placing down a pink ward it will give lower elo players an extra reason to buy pink wards. Also i notice how support players are usually one or two levels behind their peers because they have to roam around most of the time. If pink wards give exp then support player can keep in levels with their peer and enemy. The exp gain from the pink wards can also scale over time, like 1 minute into the game the pink ward can give like 5 exp if you placed it down and scale up to 50 at 20 minutes in game. This will prevent players from doing a early cheese where they buy pink wards in the beginning and get a early level 2 over the opponent. Now you might be thinking how if the pink wards scale with level will be useless because later onto the game players won't need exp anymore. That's true but generally later on in the game you probably won't have an extra item slot in your inventory so it doesn't matter. If you manage to have an item slot in your inventory by like 30 minute mark then that probably means you are a little behind, which is where the pink wards exp come in to give you a chance back in the game.

This is only an idea, but I feel like it will help players buy and use pink wards more often.
