I'm asking this as a serious question, not to start a flame war.

I have an FC on Malboro, and I have asked people from time-to-time if they would like to join. People I may have run a dungeon with that are also on Malboro, or that I ended up FATE grouping with that I chatted with and had a good time, or whatever the case may be.

Some people tell me "No thanks". I've never really gotten a straight answer as to exactly why people do not want to join FCs.

FCs provide buffs (assuming they are rank 5), they provide people to ineract with socially, they provide people who will dungeon with you, grind, fate, whatever. What is there to lose?

I see people complain about Duty Finder and such, which is going to happen, but some of these same people absolutely will not join an FC and have opportunities to put groups together within them, to make all their activities faster and easier.

So what gives? For anyone out there NOT in an FC, how come?
