I'm not sure what content you're wanting to run with others; people group to do FATES in open world, I guess, but not sure how many low levels are running round doing FATES these days. And if you're looking for a group situation that involves conversation, socialising etc, I'd say that mostly happens in linkshells/Free Companies - ie folks not necessarily doing the same content but still socialising via FC chat whilst doing so. There isn't a lot - hardly any in fact - of open world content that requires a group so people don't group. And when they do - for FATES or hunts - there's only basic conversation - 'hi', 'pull', 'wait', 'bye'.
The game CAN be very social but you need to find a long term group - usually an FC - that you like. My FC is tiny, we're all long-time friends, so I'm usually in a party with at least one person even if we're both doing completely different things. Most levelling content - namely quests - doesn't need a group, but we always run new story together just so we can laugh, complain and cry in tandem.
Guess I'm saying find yourself a convivial gang of like-minded players. They are there, just gotta seek em out
