As any other stat visible it helps to realize what kind of people you gonna be playing with and adjust own behaviour a bit. See who probably will play no matter of what and is worth to stick with, and who gonna leave the game after getting killed 2 times or not being happy with team or whatever excuse they gonna find. Yes, there could be a certain amount of bad connection situations increasing that number, but in general it does help.
Another stat visible I'd like to see could be "Time spent in hide during mini game"
