What happened to it? Now that we have a sidearm with a very similar name, vestian dynasty, i fear that the 347 vesta dynasty has been removed. Hopefully it just gets a name change.
It may also become the Playstation exclusice, which they'll probably reveal next week.

If I remember correctly the 347 vesta dynasty was an exotic specific to trials of Osiris, like you had to do extremely good or something, that may have been fate of all fools though, I don't remember for sure
