Add vision numerically for K/D/A/V vs K/D/A so stupid players understand that it is real.

During the Salem Witch Trials women were burnt alive during the 17th century if convicted of witchcraft. They determined this by observing whether or not she would float or sink in water. The outcome dictated their fate. Buoyancy had already been established by the Greeks over 1,000 years prior. Never underestimate the power of stupid people in large groups.

The number one reason why I see teams fail late game comes down to vision almost entirely. When people die their go to reason why comes in the form of K/D/A. And they are idiots. I see it time and time again. Over 75% of the jungle is not warded, and your team is down by 20 kills and an inhibitor. But Dragon has just come up. One or two go make a frantic attempt to steal it and don't know they'll die before they make it past the Raptors. The less intelligent players will start to look for reasons as to why. The most obvious reference is the KDA score. Not only were you not on their suicide mission to Dragon, but you also are the reason why their AD carry is fed. Your team has now been aced twice directly outsIt's only 25 minutes into the game and half your team is spamming the surrender button.

Vision is so important. But weak players who cannot take responsibility for their mistakes don't see vision listed on the scoreboard. As far as they are concerned.....it doesn't matter.
