Lets see..Off the top of my head,

-Level a class up one or two more levels ;.; (cant decide which one to stick with)
-Probably do the event
-Finish up all the newly lower leveled requirement story missions (super happy face)
-Uh.. Join the Twin Adder, I think.
-Level to 25 on all jobs, start dungeoning, hope I get it all done before 1.19
..Yeah.
