'03/ '04? Your basically a 'noob' again, whare the heck have you been? :P
Word of advice do you don't go crazy pulling out your hair. Ignore all this talk about Abysea, find like-minded ppl who like party/ low-man book burns and farm a lot. Like new players, it's important not to worry too much about end-game because there's still nostalgia within the community and veterans come back to play old-school: Doing ZMs, Sky and Sea stuff(maybe ToAU stuff too).
Ever since Abysea came out, it's been abused with the fact there's high level mobs and exp gaining tactics. Mobs con EP to everyone lv.95~99, so it's practically the edge of end-game but the community is expecting more to come still. It's back to the "noob-train" again for everyone!
If you going to play to have fun, then have fun. If you enjoy the game for the sake of content, playability and community... take your time. I didn't rush and I been playing since '04. If you have friends in end-game, they should be able to give you a boost through the leveling grind but for the love of Altana, at-least complete your expansions first, Abysea isn't "all that and a bag of chips"! People are still stressed over getting through the content.
