Some of us, usually just the good players, can look at all those metrics and use them to help craft a solid team comp even with random players in solo queue. Why should other players be denied the opportunity to make the most informed decisions possible just because you don't like how bad your stats might be perceived by others?
Here's some real talk for ya: if you are that ashamed of your stats that you are offended people might look at them... then this is not the game for you. It's kinda like baseball where the stats are everything and you don't see regular joe ballplayer getting upset that he doesn't have super star stats. Players want to win and somewhere in average joe ballplayer's stats is something that can help a team win from time to time and that's why average joe ballplayer has a job at all.
