Ranked Live Viewing Addition

So I often find myself with no friends online to play league with and lets be honest after a few unsuccessful games by yourself you get bored so I tend to watch the ranked games shown in the bottom right of the client. I often try to look for a game that includes a champion which I would like to become better at so I watch the game to learn and study, however I cannot often tell if the game is something I should actually study and do well to learn from. I am currently in Silver 2 and say i watched a ranked game that was less that my ranking then I've just wasted my time and even set my self back by studying the way they play. I fell like those of us who watch those games could be helped if say the tier of the players was shown in the screen or maybe just the average tier of the entire game.
