Ive seen various FC's and LS's on the forums and many of the FC's are for "endgame, raids, ect" or just a group of friends. On the other hand I have also seen a number of LS's also recruiting members for the same: "endgame raids, avoid duty finder, ect"

So, which would you prefer to use for just a circle of friends, and which would you prefer to use for game content?

I have yet to really immerse myself in the various FC's and LS in my server, so I'm not really sure which I would use for each scenario. As of the moment, I just use a FC that is just a close knit of friends. It's comfortable for us because we aren't in a hurry to rush to endgame content and such, and are taking our time. Perhaps when we switch servers we will join a big LS or a FC, but I wanted to know what others use the LS/FC for?
