I've been on Balmung since 2014. I started in one FC and had zero intentions on roleplaying after several experiences that ranged from 'bad' to 'extremely toxic'. I tentatively joined the FLEET LS in 2016 on, for me, a trial basis: if I caught the slightest whiff at something wrong or unsavory, I'd just leave immediately. 2 years later, I am still a member of FLEET's LS. I became a full-fledged member of the FC last year. I have never been involved with a RP community as open, supportive, and respectful of its players as FLEET.
All the players are funny, kind, and welcoming, and events have been well-thought out and organized. There's a healthy level of support for players to present ideas for events or advancing a character's personal story. If anything, I'm honestly overwhelmed, because I have typically been used to things going so badly I have to write off games and storylines as a complete loss.
If you have any interest in participating in some Limsa Lominsa based stories, give FLEET a look.
