I play daily amd am looking to fill my time with doing stuff rather than sit in Mhaura or Jeuno. There must be someone out there willing to take me on as a new ls member or something.
If you're a single box player, the worst thing you can do is sit around and wait for a shout to pop up or someone else to invite you to something. It almost never works, you're a needle in a haystack among the servers. Many players either static, multibox themselves, or organize groups offline via Discord.
You can try the linkshell concierge, grab a few pearls and make friends. Send a few /yells asking to join helpful/new player/veteran player linkshells, someone will bite. Also, get into the habit of reading up on current content, and then forming your own groups. Sortie, HTBF, Odyssey, Limbus, Dynamis - you can probably fill most of these with a few players via shout, depending on the time of day. Leverage all of your options, not just one (ffxiah.com). Not saying you aren't, but it will help you feel like logging in is worth it if you have something to do besides waiting on others to bring you along.
tldr - make friends, start your own groups, join open discords/linkshells
