Rayth, we are very glad that you are here playing Istaria Online and enjoying it. But I have to be blunt... If you are looking for an expansion the size of one that a game with 100,000 or more subscriptions releases, then you are going to be forever disappointed in Istaria Online.
I'm sorry I have to put it that way, but its the truth. We're all very committed to this game and we want to release as much new content as we can, but a small team of people (some of whom are part-time) cannot compete with full-time teams of 20 or 30 or more.
