I think it would be really nice with some better feedback on why I lost a teamfight. Right now all I can do is try to see who died and who just recalled. Some info like "{Top Player} extended too far and died" or "{Mid player} missed an ult" would be cool. Otherwise all I can go after is intuition, I would prefer adjusting my strategy using knowledge and numbers instead of luck and a more general idea of how the game works.
