EDIT - This news post explains everything: http://tera.enmasse.com/news/posts/new-class-the-valkyrie

------More details will be posted on April 4 along with the official Valkyrie class page (which will also announce the class release date), but since so many players have been asking about character slots we wanted to let you know what to expect.When Valkyrie releases, the maximum number of character slots will increase from 16 to 17 per server. For a lot of players out there, this is a big deal because they've already maxed out their character list on their favorite server, and this will mean they don't have to delete one of their characters (or swap to a new server) to make room for their new Valkyrie.There's also some good news for every TERA player that logs in after the Valkyrie release.If you're full up on characters, make sure you claim it on the server you want the extra slot on to make room for your Valkyrie.That's all for now but like I said above, keep your eyes peeled for the Valkyrie class page (and video guide) going live April 4.Cheers!
