LoL needs an in-house recording solution
Relying on community projects like Lolrecorder and Baron Replays is inappropriate, and these tool developers are just volunteers who are not privy to updates that may effect their programs.
At the moment, neither recording tool is functional for self-recording. Riot needs to ship spectate recording with their own client.
It is no longer the fledgling moba of many years past. Consider it growing pains. You have outearned Blizzard. You're rich. Please alot the resources for this.
EDIT:
I'm not referring to video recording, like FRAPS. Rather replay files that can be played via the spectate tool.
