I have been through 5 dungeons now and have NEVER been able to select Need. Even if I am the ONLY person who can wear it in the group. I am playing on the PS3 and wondering if I am glitched?

Also, how the hell does greed work? Because I just ran a dungeon and only ONE person got EVERY single item. Even ones that only I could equip (in which it would not let me select need, only greed).

Thanks in advance.
