include team performance when measuring our own score

It would be great to have a statistic which indicates our score compared to the performance of others in a game. Becoming fed and reach a score like 20 kills and 2 deaths can mean something when your team also performed well and did great overall, but can mean alot more when your team performed bad and you had feeders and bad players. The same applies when you had a bad game and terrible stat, it can very often be result not so much by your skill, but by your team performance, if they fed the enemy etc. I know that might be very complicate to do, but it also will be much more accurate.
