I know you can abandon it and pick it up again at the correct level but it seems like im so far behind now for a level 9. I'm assuming there's no way to jump ahead other than going through the mission chain.

^Is there a way? I was level 2 and was on the first chain and I decided to join a mission group and reached level 9 when everything ended. Can I skip these missions or do I have to complete the chain?
