Thorn is the only hard weapon you actually have to earn right now, I like that.
This, Thorn was the coolest of the exotic bounties.
Once it gets its power tuned, should be a lot more satisfying.
Honestly the exotic bounties tying little bits of story to the weapons was really neat, and more interesting by far than spending some coins at xur or lucking into one in a weekly.
Not that they were all well executed, or rewarded worthy weapons mind you, but the basic idea is sound.
I have mixed feelings about the forced pvp nature of some of them. It doesn't bother me at all because I love pvp, but for people who dislike or actively avoid it, it's a real barrier.
On the other hand, there are some people who have no interest in raiding or pve content, and there's no other way to get raid weapons or armor.
Ultimately they've got the data to see who tackled what bounties and struggled with them, so when they finally get around to patching this game maybe we'll see some changes.
