What exotic primary am I missing? (Destiny)
I'm currently lacking 5 year two exotic primaries that need discovery. I have every one from year one. I know I'm missing are Jade Rabbit, First Curse, Fabian, and Tlaloc.
That's four. What's the fifth? I'd be a Taken King exotic since I haven't discovered it.

What exotic primary am I missing?
I have all the primaries available on Xbox and I still have two primaries open. Fate of All Fools and Jade Rabbit were my guess, but a friend said he knew playstation players who had Jade Rabbit and still had two open.

What exotic primary am I missing?
The moment I bought my Y2 MIDA, another unknown primary appeared, so instead of having 5 in the top row on the right, I now have 6, of which I'm missing 2 (one is Tlaloc, the other is unknown). This is on PS4. Before buying the Y2 MIDA, I only had 5 in the top row on the right, of which I thought the extra missing one was MIDA.

Immediately after the most recent update, anyone who purchased or unlocked the year 2 version of Mida noticed a new primary exotic icon would appear in their terminal. The appearance of this extra primary is directly tied to Mida... it won't appear due to purchasing any other weapon.
2 most likely answers are 1) there is still a primary exotic that is technically in the game but has not been made available/revealed (Fate of All Fools perhaps?), or 2) It's a bug.

Price of Exile
Some suspect that the year 2 MIDA opens up a slot for this exotic weapon, but no one knows how to unlock the quest for it. I came across this video:

Price of Exile Was designed entirely by the Reddit community

Ok. I didn't vet any sources..
was just something I came across that fit the question. Would be cool if Bungie made a community creation, though.
