We'll just have to wait for it.We are as excited as many of you to get into Mordor, but we have some unfortunate news: we have to adjust the release date. While preparing over the weekend to release the expansion on Monday, we discovered an issue in the build that impacted the ability of monsters and NPCs to move around correctly. This problem was specifically identified in older content.
While correcting this issue is not a problem, the process to correct it takes too long to be able to release Mordor on Monday. So, we have to adjust the release date. We will have more info on the release date soon. We will know a lot more in the next 24 hours or so, and will pass along the info as soon as we can.
