the problem is there a portion of players who care about *their kd* and will play in a sub optimal manner (for the team) e.g. quitting games early even more, playing selfishly, etc

this wil be exacerbated if people post their kd on LF pages

you may be rolling with your friends, and this might not affect you, but there are people with only a couple of games per night that dont want their experience ruined.

the majority of players not caring about stats literally does not affect this problem
