Pretty much this. I had a brief impulse to rejoin last week until FFXIV was up--maybe try and finish up Wings of the Goddess, and all that. But the idea of doing all the genkai quests to get access to level 99 (I was level 80 RDM and SCH when I quit), complete Abyssea, complete WotG... it just sounded like too much of a hassle when most of the people I know no longer play. Throw in that my favorite class (RDM) is something of a joke these days and, well, I can't say it appeals.
Starting from the very beginning? Forget that noise.
