Originally I was going for 4 seals: Cursebreaker, Chronicler, Dredgen (procrastinated like hell), and the Foreunner one for this season. I got Cursebreaker 2-3 weeks ago and accidentally got Dredgen a week after. That leaves the annoying timegated seals.
Aside from that, I'm trying to get any remaining exotics/catalysts I don't have. I recently got and started Outbreak's, and both Vigilance Wing and Suros finally managed to drop during Iron Banner while I was finishing up getting Revoker (again, heavy procrastination). As far as catalysts go I need Acrius, Telesto, and Sleeper. I still need all of the raid exotics too.
I have nearly all of the pinnacle weapons; just missing the crucible ones. I'm on the final step for Mountaintop where I have to get to Fabled, but I'm waiting until I get to the 25 comp matches for Redrix's so I can bang both of those out at once. I don't have any plans on going for Not Forgotten, but I may finish up Luna's Howl.
So it looks like I still have quite a bit to do.
