I would like to see some larger group content, but this game was meant to be casual by design, so apart from Crystal Tower and Frontlines I don't know if this will ever come to fruition. Like others, I feel an FC could be populated by a static raid group and maybe some casual players that would be decidedly non-raiders. When you start getting more than one group of raiders in a FC it causes segmentation since it's just not feasible to swap people between raid groups in most cases. Schedules usually don't mesh and then you have group synergy issues you have to work out.
