I don't have a LS but the FC I'm in are active and talkative. We're always talking amongst ourselves either through game chat or PS4 party chat. We're always helping each other out too. We have all sorts of players. We mainly play DPS, but one member alts a tank and I alt both healer classes.
I know it's not what you're looking for since we're a FC and not a LS, but maybe you could consider us in the future. The FC is called Legacy of Eorzea (LoE). /tell Mathye North if you ever fancy it.
And good luck finding a suitable LS
