A quality of life improvement that would greatly help players warding, especially low elo.

Long story short, a sightstone should place an average of 50 wards in 30 minutes and a yellow trinket should place an average of 20 wards in 30 minutes. Low elo barely uses 16 wards per player every match (sightstone included), and every ward not used is wasted gold and potential (75g x 20 or 50=? ), it also costs nothing and being too lazy to press ONE button is not an excuse.

So what can be done about it to help players that genuinely forget about warding since they don't have this kind of muscle memory?

We could simply add a discrete ping sound (maybe made just for this occasion, that would be nice also to hear a nice sound now and then just like it has been done for the OMW pings) that reminds the player every time their warding trinket had 2 charges and now the timer for a third ward has elapsed, i got this idea thanks to the purple flashing screen when herald is about to expire, adding a notification without the screen flashing (which is suited for something like a herald which happens only once per game) would greatly help people in their warding quest, it shouldn't be too loud of course because a player could be sitting on 2 wards on purpose because he's holding them for later maybe, but since many players don't pay the necessary respect to the warding component of the game it would come in handy.
