(Post here if you haven't gotten your quest yet.)
Personally I've done all 4 Shiro on all 3 characters since ROI dropped. + each vanguard every day.
I've done the other 3 exotic quests in the book and this is my last..
And all for a gun that's super garbage and nerfed to nothing. I'm pretty sure the palindrome that he is selling 2 tapped me in crucible yesterday. And it is legendary lolz, the Thorn needs to be reworked
EDIT: 47 shiro hand INS later and I got the jagged Thorn quest to drop. MY QUEST IS OVER. BC THIS IS NOTHING LIKE YEAR ONE QUEST.
