League implant a replay system???

I posted in another board, but im not sure if it was the good one xD. I always loved to watch videos about league plays, outplays and would love to share or review mine or others. I tried lolreplay and it keeps crashing my league patch after patch. Also tried the baronreplays (or whatever it was called) alternative and it does the same problems. Even if i didn't even opened the programs (completely close them with task manager) league continued to crash. I had to completely uninstall these programs for my client to function properly. I also tried fraps and other pc screen recording programs to record each game, but it takes a whole lot of space and I have to crop/edit or delete after every game (which I don't like the idea of doing so). All that to conclude that riot should implant a sort of system that records every single match and has a limit and deletes the last ones when there getting old and also let people download/ crop/ edit these matches because they will eventually be deleted (following match history or maximum data capacity). I know this could be and cause alot of trouble for riot, but im sure it is possible, and of course there are a million of matches played each day, so it would take enormous amount of space, but as I said, they dont have to keep every match, they could put like an option, that after a match, you can download it instantly or save the video file and it auto deletes after 10-24 (whatever the time) hours. Anything so that I could rewatch my plays and analyse how I could become better, and Its just a cool idea to have overall.
