I've tried, but no go. /:
I'm going to be one of those old annoying players that reminisces on the "good ol' days," but it's how I feel. I remember level 70 being such a huge accomplishment, and now I have more fourth job characters than I'd care to count, and the game is so different. It's no longer about the friends, you know? It's way too much about having the best gear, or the most mesos, or the highest levels.
I went back to farming earlier this year. I got up to around 20 billion or so mesos, but ended up selling it and giving it away and quitting. I don't have the heart to delete my characters, but they're pretty nekkid for now.
BUT, I'd be happy to help anyone if you guys need it! Advice-wise, anyway.
Edit: Went back for a day. Went from nothing to level 70. This game is too easy. ;-;
