Strangely I've had the completely opposite experience in this game. I had 1 friend currently playing on and off, sometimes only online 1 day a week, but he got me an invite to the FC he was in and from day 1 everyone in that FC wanted to do things together. Whether it was simply doing the roulettes, doing Deltascape, maps, farming old raid bosses for mounts, or having a few hours decorating the FC house it felt like there was always something going on that I could get involved in.
It's probably the only MMO apart from SWG where I have seen people do things together outside of raiding and dungeons.
