Right now, the game doesn't have as many players in general as when a patch releases due to the expansion coming in a few months. However, there are always groups in PF for end game content, and when the expansion hits in June the game will be booming again. Between now and the expansion I would recommend gearing up your favorite job and leveling as many as you can when you have time. All the jobs in this game are extremely fun and the more you play the better you will get at your main as you will see what you can do to help other jobs in the party as well as get a better feel for mechanics.
