What i was thinking that could be added maybe in a future expansion something called a Free Company mission which require around 24+ people to do and once you do it the FC gets money put into its bank and the FC members get paid every 24 hours from the FC bank, the missions could reset everyday and have it changed from 24 man mission (alliance) to kill a boss e.g. a world of darkness boss but everyone is min ilvl. it could also be something like a gathering and crafting mission. The guild missions could give around 10m gil (all prices are just examples) to the FC chest, and everyday the FC members could withdraw a daily amount of gil e.g. 25k gil, and the longer you are in the FC the more gil you can get e.g. every month it increases by a set amount.

e.g. join start at 25k, 1 month you get 30k, 2 month 40k, 3 months 50k, 4 months 75k, 5 months 90k, 6 months 100k then it will stay at that price for the rest of the time in the fc.
