The notes aren’t necessarily super clear. But I think we have a similar understanding. I’ve read them again and it seems like you may still be able to get duplicate Quest Exotics but not from random Engram drops. However, the way that the notes read to me was that they are making it so that duplicates are one bucket and Exotics not in your collection are another. So regardless of how many duplicates you have they are pulling from the same overall chance to drop; i.e., no matter how many exotics are in your dupe pool you still have the same chance of getting a new one.

So from the way it reads to me having Quest Exotics available in the Engram Pool is entirely separate from the Exotic Dupe protection meaning that the only impact removing them has is that you’re gonna need to spend more materials to infuse them - not that you will gain a higher chance of getting a new Exotic.

Full stop i could be misunderstanding their intent. But that’s how it reads to me.

Yes Exotic Drops in general haven’t felt very good. I have had better luck than a lot of folks. Haven’t gotten the Exotics I’ve wanted. But That doesn’t mean that I wouldn’t like to be able to inexpensively upgrade the ones I’ve done Quests for and would like to keep using.

But the assumption I am making based on the notes function with arbitrary numbers:

When you’re receiving an Exotic, we will take into account all Exotics you’ve found, and weight them against Exotics you have yet to acquire; this lowers the chances of receiving Exotics you already own

All Exotics you have found are a 50% chance, Exotics yet to acquire are a 50% chance. Regardless of how many are in each bucket.

Exotics that you do not yet own will be individually weighted much higher than duplicate Exotics

If you take the list of Exotics you don’t have and split it up the individual probability should be higher because there are less Forsaken Exotics.

Yes, the function assumes you have a certain volume of RW/CoO/W Exotics.

As said, I could be wrong in my understanding.
