Blizzard is asking for testers for their new desktop app that is currently in development. This app is "designed to improve the launcher experience for all Blizzard games and streamline the ability for players to get into their games."
To help with the testing, all you have to do is opt in to any of the game universe betas from your account management. An e-mail will be sent to you when you are selected for the testing.
