The client automatically records every match for the player to watch later if he or she desires. DotA 2 (yes yes, bring on the hate) has had its own in-game recorder since beta. Why Riot has not released its own match recording system I do not know. Last, the way Riot builds out and updates League itself means that any recorder is destined to break after patch day. Some video I’ve seen of Baron Replay’s recordings have graphical artifacts and glitches. The English translations are rough, and the interface provides less information for a match than LoL Replay does: no KDAs, items, gold earned, CS, etc. Notwithstanding the security issues, the program isn’t much better than LoL Replay. VirusTotal, for instance, identifies three potential threats in the program. Since Baron Replay is fairly new and from Taiwan, there’s some question as to its safety. Baron Replay, produced by League players in Taiwan, is the only other in-game Spectator Mode recorder available.

Using an alternate program for replays isn’t much of a solution, either. They are not as efficient, and do not produce the desired video, as an in-game recorder like LoL Replay does.

They require a lot of CPU power, slow the game and reduce FPS, produce large file sizes, and record not in Spectator Mode but from the player’s perspective of a game. Outside live recorders, such as FRAPS, are not a viable and attractive alternative for many players such as myself. All LoL Replay users go through this agony of broken old replays, waiting for LoL Replay’s creator to update the software, each time Riot releases a new patch.

LoL Replay records and plays new matches on the 4.3 patch just fine, but matches from patch 4.2 require some manual adjustments to work, and matches from patch 4.1 and earlier bug splat before the game loads. Yet again when Riot released a new patch (4.3), LoL Replay broke.
