So I've been trying to get Izanagi's Burden and I've reached the point where I have to do that raid and get the crystal or whatever. I need to know if I'll be able to finish this exotic quest prior to shadowkeep launch. Also with other exotic quests like Bad Juju, Outbreak Perfected, and Whisper of the Worm. I would like to acquire all of those, but I started quite late in the season and also don't have a fireteam to do the respective quests with. After the season is over and shadowkeep launches, will I still be able to go get those guns?
