Tomorrow we will be updating Legends with an incremental update. We anticipate maintenance beginning around 9am ET and taking a couple hours. Stay tuned for updates on @bethesdasupport on Twitter.
Note: Once we're out of maintenance, we'll be putting up a news story on the new changes in the game, including several updates to cards. As I will be on a flight to QuakeCon (woohoo!), I can tell you that the notes will likely surface first on legends.bethesda.net.
On behalf of the whole time, thanks in advance for patience!!
