I'm not even worried about the weapons at the moment, it's more about doing the rest of the story. Outside of the fanfiction of the Wandering Minstrel (aka, the EX, Savage and Ultimate fights), I think Bozja and Eureka are the last two bits of story I haven't done. I managed to complete every side quest currently available towards the end of last year, so behind that it's mainly doing stuff like maxing shared FATEs and that kind of thing - I know that's not story, just unlock stuff, but still something I need to get around to.
