I'd like to know if there is a way to rewatch your most recently played matches to maybe learn from your mistakes or enjoy some of your better plays. Also if there is not would there be a way for Riot to implement this into the game for Summoners who would like to learn or see why they did well or badly?
There are a few programs which save your replay file as you play (they just copy the match using Spectator mode). The one I use and recommend is BaronReplays. There is also LolReplays but it feels kind of scammy having ads and stuff, but it does do the same thing.
The files are extremely small (are not raw footage) and are played back through the Spectator client so you can pause and move around just like if you were spectating. It will also record anything you spectate. It won't record anything that can't be spectated normally (like vs. AI games).
Usually you can go to na.op.gg and you can usually spectate your older games.
