Tough topic to answer. I started in Version 1 and had a great linkshell. Most of us kept in touch through guildwork even a simple hello here and there. At relaunch of ARR 2 years later those that stayed on the server were all in a FC started by old linkshell members. First few weeks were fine after that it turned into the inner circle that played nonstop just farming tomes and didn't care about anyone else. Once members started getting their relics handed to them then it really got bad. Nose up in there air I'm better than you syndrome. Close friends of mine got disgusted, fights broke and out and even some quit or left the FC.
We didn't have that in Version 1 so I never expected be a ARR or the community to be a bunch of snobs. One of my close friends transferred servers and said the community was fun and so was his new FC. Maybe it was a legacy server thing I don't know. I would transfer if they would let me take my gil with lol.
