World of Raids has discovered something that might give Hunters a momentary attack of Angina: Thori'dal, the Stars' Fury has been found in the current game files, and while it still looks pretty tasty, it's also look weaker than the last known stats from the Pre-PTR leak. Namely, it's lost about 10 base DPS, having dropped from 148.7 DPS to 138.8 DPS.
Now, it's hard to call this a "nerf," perse, since the bow hasn't actually appeared on any live or test server yet as an actual item. It's possible that the pre-PTR leak was a hoax (not likely though, since it got the other stats spot on), or that Blizzard's internal testing made them think they needed to tone back the damage a bit. It's a bit of a blow to think what might have been with the old damage anyway, of course.
That said, Kil'jaedan isn't even killable yet on live realms, so the stats could change again before it drops. Even if they don't, it's still an awesome bow that will make the Black Bow of the Betrayer look like a peashooter for damage, and comes with the added bonus of a free bag slot, so I'm sure there will be plenty of Hunters aiming for it, and good luck to them. My Hunter is still going to be holding out for a Legendary Gun out of Thor Modan.
