I have the feeling that considering that the Tribute Hall and pretty much the Leviathan is being vaulted along with everything else this November 10th, I think that it should be cheaper to buy tributes. Think about it, the raids like Scourge of the Past, Leviathan and its raid lairs, and Crown of Sorrows are getting unlimited ammo before they get vaulted, so there should be something similar like no longer require boons of opulences and buy tributes cheaper to access the bad juju before it disappears forever. Now don't get me wrong, I don't know if Bungie will even have the slightest care of noticing my post. But all I'm trying to say is that it will make not only my life easier, but the rest of the Destiny fan community as well.
