So I recently purchased the Ring of Scale expansion after last buying The Broken Mirror. (IE I never bought EOK). I understand the basic 10-Familiar Key Ring was a part of the EOK expansion however when you buy the latest expansion you have always gotten any earlier expansions you didn't have, plus the associated UI features that come with them. This didn't appear to happen when I got ROS. Is this intended? It seems weird as that was one of the marketed UI changes of EOK and purchasing ROS gets you ROS and EOK.
No they changed keyrings and they are not included in "make up" expansions. They are available in marketplace now.
