Official LoL Replay SysteM
There should most definitely be a built in LoL replay system that is very easy to utilize and access. Lots of people talk about LoL Replay and other replay clients but most of them are illegitimate and not that great. It's about time for an implementation of one in the game that can be turned on and off in game setting and such.
Please @Riot take this into consideration. I will poll if it counts for anything. Thank you for reading this suggestion, and summonses please leave an honest poll vote :)
