Sniper to be

[Huscarlton Banks]

You should probably get a fiendish as quickly as possible, the price of legendaries will keep rising due to higher demand as more players hit t3+. Even if goldsinks are added, the price will still rise a lot compared to other items because most crafted items just aren't as good.

I'd say the fiendish bow is definitely worth it though, since it both fires faster and does more damage than the warbow.
