You know what we need? more FATEs like Odin and Behemoth. Even some that are targeted for low-mid leveled players. We need hidden secrets scattered through the world, open world mini games (gold saucer is a start), open world dungeons like in 1.xx, and an alliance treasure hunt as mentioned would be amazing...it could reward tomes, gil, crafting items, and some decent gear. Maybe these could only be made so that you can participate in one once a day. Because of course something so fun will have lockouts >_>
