I really hope SE incorporates the 12 into the main story line as pivotal characters, akin to how they did the crystal warriors in FFXI. Right now the story of the 12, their history with Bahamut and old man Loui is the major draw to this game for me. The major quest lines (nation, ZM, CoP) were the most memorable aspect to me in FFXI, I hope for the same in FFXIV.
