FFXIV has quite literally a Fellowship and Community Finder to look for groups which have similar interests as you. Be it Mahjongg, Role-Playing, Try-Harding old content or seeing for LGBTQ interactions. And the rest is done over Discord, because that is for sure a better communication tool than whatever the game devs can come up with. Even the content thing is not true. There is seperate content which absolutely requires cooperation, schedules outside the cookie cutter main content like Bozja and Deep/Criterion Dungeons. More similar to old school MMOs. I'm fine with a diverse array of content.
Hell, I'm an oldass, I remember seeing people talk about Linkshells with certain interests on the forums and in-game. FFXIVs sense of community has been awesome for a long time, and they've only improved it from what I've seen.
Yep. Was just about to say this. FFXIV has a strong community, and the director actually listens to the community. Like with Bozja in 5.x content, it was so fun and a really nice way to get a relic weapon and have a good time with friends. With 6.x they didn’t implement anything like it and the community let them know, so they have said that they are doing something similar for 7.x. Some midcore/harder content that’s accessible to everyone.
