There's been a lot of questions regarding the content release for Onyxia and we'd like to answer some of those questions best we can. Here we'll share a concise listing of information from both the announcement and answers we have for questions so far. We are reading your questions and concerns and are giving answers where we can, and if it is appropriate for us to give that information at this time. The compiled information here will be updated as we have new information to share, and I will make a post when new information can be found so that you can check this thread for new posts.
