How To Make/Show that Supports are Very Helpful and Good in the Post Game Stats! (idea)

I main support a year now and I always see supports getting no recognition being a mid gold player. People only recognize how good supports are with the obvious playing making supports like thresh. But I thought of a way to make/show that supports do help the team (in terms of like kills).

     -- That idea is that have a post game stat that shows how many wards were placed that happened to be around a kill for each member.
     -- For Example say if it's mid game and you are on the red side and placed a ward on the raptors with your ward. And then say if you catch the enemy jungler doing the raptors and then say 10 seconds later you as the support and your jungler come and kill him as he is walking towards the river. 
     -- In the post stats,there would be a stat that would say somehting like"ward kill proximity"(that you placed within 20 seconds) and you would get 1 point for each time it happens. 

A good amount of times we get kills is by setting up deep wards and collapsing on people who are caught out. If this does get input, I think a lot of people would see that supports are good
