what my friend did was he got the level jump and went through the story without any blockages. he could solo dungeons if he wanted or grabbed one of us to join him unsynced to rush through them and enjoy the cut scenes. If you like the story but don't want to wait on level and gear grinding getting the level jump might help just so you don't burn out grinding up levels and gear. Though seeing your level 54 (lancer?) it might just be better to grabs some good mates and press through.
