Team Vision Score should be implemented to the interface
Vision Score is something that is recently introduced in the end-game stats. I'm not sure how exactly it's currently calculated but it seems to be a valuable number that reflects the differents between a team that has vision controle and someone we doesn't have it.
A simply update to the interface: https://i.imgur.com/9qyiyFT.png
Often I have seen games lost because lack of vision controle. If you on the winning team and all of a sudden they slowly start to lose their lead it's often by the lack of vision controle. Most players aren't aware of this and start to get frustrated because they aren't aware of the reason they are losing. If the support starts telling them why they are losing. They often just get flamed upon. It's not like they have much proof regarding the issue.
Useally the team with the most vision controle is the one with a lead like this one: https://i.imgur.com/nqatOs1.png
