All this made me think of a workaround: Maybe an additional game mechanic can be added; A character can only engage a boss (or named) fight once every a specific set period of time. Let's say half a day for nameds and half a week for bosses. That means that there is no reason for bosses and nameds to have large pop times. As soon as a boss is killed, let it pop in 5, maybe 10 minutes. It doesn't matter, as no person from the same team can benefit. Just move on to another boss you haven't killed these past few days.
What do you think of this one?
I think it won't work.
Very short respawn times will just lead to more mats in circulation.
What happens when you have a mixed team, some that have done it already and some that have not? There's also nothing stopping someone engaging a boss solo and a team healing that soloist and sharing the mats, then they can just rotate and do it again. Imo it's a messy way of doing it.
