In-Client Game Recording/Replay

Posting this to suggest to the dev teams to incorporate a way to replay our previous games, wouldn't be very difficult at all to implement and would be a great feature for those of us who like to analyze our past games in order to recognize mistakes and improve our gameplay.

I understand that there are external third party applications/programs that provide this feature (i.e lol recorder) but it would be pretty sweet if it were introduced into the client itself, being able to watch replays of games on our match histories (possibly even those from others match histories).

This would even probably be helpful in punishing people for scripting and so forth which has been a problem on the game (though it seems one that has been getting a lot better with more and more ban waves and people getting caught).

The main reason for the feature would just be to be able to watch replays of our games without having to use a third party recording program.
