Well If all my friends quit I would try to make more, assuming that doesn't work I would try 1 of the servers in the Chaos datacentre (being more closer to home).
If that doesn't work I become a nolife raider clear god kefka and just quit the game till xxxx content.


Tldr; friends make the world go round for me in Eorzea, if I didn't have them I would go learn how to irl
