I guess that's the effect of having built a theme park MMO.
Back in 1.0 it feels like we were forced to socialize and work together because it was really hard to progress by playing solo. You almost had to have a static just to get through the main story.
I still play with my old 1.0 group. We went through so much together like the frustration of trying to take down Batraal in Dzemael Darkhold back when it was actually hard to clear dungeons, or the joy of actually coming out of the Bowl of Embers alive together instead of a heap on the floor that other players standing around had to charity raise. I suspect Tanaka-san designed some of those systems intentionally, but that's not what much of the players wanted.
Since ARR I wonder if it's more limited to the optional raiding content for bonding through fire. Everything else is easy to just do on your own.
