This is something i would like to see add in this game, and shouldn't be that hard to implement.

Have some achiviments that we can have solo but in a FC level, like raids, activites even glamur if they find a way to implement that. Also FC have their own achievements and maybe a Achievements rank for the FCs.

Like:
Player:
- Clear Labyrinth of the Ancients in a 24 FC Group - 1 Time
- Clear Labyrinth of the Ancients in a 24 FC Group - 5 Times

FC:
- Clear Labyrinth of the Ancients in a 24 FC Group - 1 Time
- Clear Labyrinth of the Ancients in a 24 FC Group - 10 Times
