Well for me it would have to be something like Chains of Promathia. That, I think, was the best expansion this game has gotten. It had an awesome story. It was something hard to achieve but felt soooo rewarding after winning the battles. I felt good about achieving that. I was really happy about it. In contrast, Adoulin felt somewhat easy and rushed. Of course there are other aspects of Adoulin, but story wise it wasn't the best. I don't mind not having new areas, all I really want is a good extensive story that is not so easy to do. Something challenging and rewarding. Something I can say with a big smile that I accomplished it. Of course there has to be room for innovation and new stuff the developers want to try. New systems to add, maybe a job or two if they want. For me, i just want another awesome story.
