Some may disagree other may agree. Some if not all of the current player base remembers WOTG for FFXi. Now in that expansion you can go back to the past before the present time.
Now lets look at FFXIV 2.0 and lets look at the current FFXIV. Here is a rare opportunity that Square Enix has on there hands. Once FFXIV 2.0 is released, in stead of SE abandoning the current story they could add it in as the pre-story. Basicly those of us who have done it wouldnt have to worry about doing it again, but new players would get to experience FFXIV 2.0 in the present world and past world before meteor strikes. Now se could upgrade this pre-story to have all the current improvements that 2.0 will have.
