Hunter - Tranq Shot to dispel enrage mechanics and magic effects (src)
Tranq Shot will soon be able to dispel enrage mechanics (i.e. Warrior Enrage, Rogue's Hunger For Blood, etc.). It should also be able to dispel Druids' "Owlkin Frenzy" effect. Also going to lower the cooldown.
In addition, Tranq Shot will also be able to dispel magic effects, and we're removing that from Arcane Shot.
Hunter - Future Chimera Shot improvements and Serpent Sting buff (src)
We'll be doing some improvements to Chimera Shot. We'll experiement with it refreshing the duration of the sting instead of consuming, and adding some base damage to the shot as well. It should act as an Arcane Shot replacement, doing significantly more damage (especially if serpent sting is on the target).
Regarding Serpent Sting, we'll bump the damage bonus you get from this effect up. We also want to make Serpent Sting more usable for Hunters.
Hunter - Mana issues (src)
The mana cost of new ranks is not just an issue for Hunters. We're looking at lowering the mana cost of all new ranks among all classes. We also intend to do some improvements to Aspect of the Viper. Not to mention mana return mechanics in each of the tree's (Invigoration, Rapid Recuperation, Hunting Party etc.)
Hunter - Explosive Shot (src)
Explosive Shot is intended to be three shots in one cast. Imagine Arcane Missiles, but not having to channel it. The spell isn't quite there yet, we're still not sure if it needs the AOE or not. It's not intended to really be AOE utility.
Hunter - Low level pets (src)
We haven't given up hope of fixing up your existing low-level pets.
