So Riot has released a beta version of the launcher that they have rebuilt from the ground up in hopes of soon having a better patching system and also to help support a future replay system (hell yeah). Anyone can get the launcher and they actually want people to try it and test it out for bugs and such. It won't be released until they have an adequate amount of bug reports and fixed them all. But I have tried it and so far there has not been any noticeable bugs of any kind. It takes a few minutes to convert from the old launcher to the new one, however I feel that it is well worth it. If you want to try it head on over to the LoL homepage and there will be a news link that will direct you to a page telling you how to do it.
