The potential for battle strategy. I loved this in FFXI, but this game has far more vast options. imagine having 15 people group together for an epic quest, with a good leader, we gather before embarking and organize. We need this many Fire spells, who has them, equip them. Need fire debuffs. Cure? Raise? Roles that are not defined by seeking a Paladin etc. Roles defined from quest to quest and directed at each unique battle scenario.
