TBH, the steps for the new triumphs, bad juju, and bad juju calyst are way better than alot of previous quests and ways of obtaining exotic catalyst. What we got with the tribute hall has a clear path, it my be lengthy but you get guaranteed progress towards your goal. With the exception of whisper, outbreak, Polaris lance, and now bad juju every exotic catalyst is 100% RNG and you might play for 1 hour or 1000 hours before you get one.
Acrius Catalyst was RNG from Prestige Leviathan
This I didn't know, just figured the quest I have to run prestige Leviathan gave it. I never felt the need to do any raids after how dissatisfying Leviathan was in regards to rewards. lol
