Without doubt, you may aware that Hunters have some nerfs coming to us in 3.0.8. By now, the upcoming changes we will make discussion in-depth. Let us get down to it in detail.
   Hunters of all specs are doing too much damage in PvE in particular Beast-master. We tested this a lot internally in beta and knew Hunters were high but we hoped other classes would be able to catch up in a way they have as yet been unable to do. We want to be careful not to hurt hunter DPS too much in PvP, so we are taking most of the damage out of Steady Shot and Volley. Beast master Hunters are in addition losing some of their pet DPS. We still want BMs to have the best pets, but pet DPS numbers are a little high at the moment. We are also still concerned about hunter survivability in PvP and taking the opportunity to jazz up Deterrence into something that looks and plays a little more interesting.
    These are not all of the changes we are working on for hunters, but those changes we feel are ready for testing. We hope to get these changes up on the PTR so players will have a chance to test them out and respond before they go live.
    Steady Shot now only gains 10% of attack power as damage (down from 20%). Given that Steady Shot damage is mitigated by armor which is a condition that is aided significantly by the liberal application of Armor Penetration, it's not that impressive as a shot, by general standards. It's got a quick cast and low mana cost, which makes it a great "bread and butter" shot for most rotations.
Volley reduced the damage by about 30% for all ranks. Note that AE damage from many classes is very high and we are looking at all of them. In particular, Volley had reached the point where some hunters were using it to the exclusion of most other attacks.
We totally understand why they are nerfing Volley. After watching the 10k+ Volley crits flood our screen in quick succession while running H-Naxx, we couldn't help but think it was only a matter of time before the afterglow of love-making to this poor neglected ability paled into the horror of a one night stand.
In every heroic raid we've done and that would be all of them at this point, we've found some excuse to use Volley. In Naxx, there were plenty of large groups of mobs to clear. In OS, there were the packs around the outer rim to clear to get to the drakes. In Eye of Eternity, Volley was great for dealing with the low-flying mobs in phase 2 while running from shield to shield where getting adequate range was challenging. And in each of these scenarios, we would watch DPS output skyrocket, taking me from 10th to 5th place on the DPS meter in a matter of moments.
Readiness no longer affects the cooldown of Bestial Wrath.
Deterrence has been completely overhauled. It now allows you to deflect 100% of incoming melee or spell damage for 5 seconds, but prevents you from attacking while active. You still must be facing the attacker to deflect the damage.
Kill Shot cooldown reduced to 15 sec (from 35 sec).
Kindred Spirits now only grants 3/6/9/12/15% pet damage.
Serpent's Swiftness now only grants 2/4/6/8/10% bonus attack speed to pet.
All hunter pet abilities with a cooldown longer than 30 sec have been moved off the global cooldown.
Growl threat generation increased by 20%.
Call of the Wild now benefits only the hunter and his or her pet.
Spirit Strike reduced the period on the dot so it will work better with Longevity.
Improved Tracking now benefits damage to all included creature types as long as you are tracking one of them. You don't have to swap around what you are tracking as much.
Aspect of the Wild now raid-wide.
In the end, it's important to realize that all of the proposed changes haven't even been run through the PTR yet for testing. Make sure that lots of the changes have been listed are not in their final forms yet. And there's hope that the list will be expanded to include some more PVP improvements besides the change to Kill Shot.
