I'm playing FFXI, but I'm on Asura, sorry.
sad
I don't love it, I gotta be honest. I'm really only playing it because I can't stand saying "I've played every FF game....except 11". Either way, it has it's charms, certainly. Mostly in the later expansions. So far I've finished the original storyline, all three nations storylines, Rise of the Zilart, Chains of Promathia, Treasures of Aht Urgahn, and I just started Wings of the Goddess the other day.
Rise of the Zilart's been my favorite so far.
I would highly recommend you get your hands on some Trust allies. You can try to party it up with other players if you like, but having Trust allies allows you to solo pretty much the entire game. I've solo'd everything so far with a 99SMN/49WHM, with a party of Trust characters pretty much anywhere that allows it.
Also once you hit level 30, you can enter Abyssea, and skyrocket up to 99 in a literal matter of hours. I think it took like 9 hours or something to level all the way up. Though you will need to complete the limit break quests in order to unlock all of your level caps (there's 10 of them, every five levels starting at 50). Those were actually a real pain to do. Though I managed to solo all but two of them. I think they were the 55 and 75 caps if I remember right.
And get a linkshell as well if you haven't already. A lot of people will be willing to share one if you ask or if they help you out with a quest. They're full of veteran players and a lot of them will be more than happy to give you advice or help you accomplish difficult tasks.
Either way, welcome and I hope you enjoy your experience!
