It's not so bad, don't be too intimidated. You come across some real jerks in Crystal Tower, and Duty Finder parties, sometimes, but you'll probably meet a lot of cool people, too.

Do you have a linkshell or a free company? It may help to run content the first time with a group of friends like that if you can, I know that I typically do that if I don't want to look at a guide online, and we always have a great time.

If you were on Balmung I'd offer a hand, and I'm sure there are others on your server who feel the same way!
