I actually kind of miss having to find a full party to start instances... Sure, it was a pain in the ass at times, but it also created.... comradery, in a way.
I made so many friends just pugging for moogle or ifrit.

I also miss my old linkshell buddies, but that has nothing to do with changes with the game, just personal choices.
Well, maybe slightly to do with changes, since my old server became a JP server.
