(Please note that I will try to keep this list updated as the PTR Progresses.  However, as with anything on the PTR these may not reflect the current implemented changes, nor the what will finally make it into Patch 3.2.  As always the Official PTR Notes can be found at: http://www.worldofwarcraft.com/patchnotes/test-realm-patchnotes.html.

If you feel anything might be missing from this list that effects Hunters please contact me at brigwyn@brigwyn.com.  Thank you.)

Items: General

• Resilience: No longer reduces the amount of damage done by damage over time spells, but instead reduces the amount of all damage done by players by the same proportion. The other effects of resilience (reducing critical chance, critical damage and mana drain effects) have not changed.

Classes: General

• Replenishment: This buff now grants 1% of the target’s maximum mana over 5 seconds instead of 0.25% per second. This applies to all 5 sources of Replenishment (Vampiric Touch, Judgements of the Wise, Hunting Party, Enduring Winter Frostbolts and Soul Leech).
• Silence, Strangulate, Silencing Shot, and Arcane Torrent: These abilities will also apply a 3 second interrupt effect against non-player controlled targets, making them more versatile against creatures immune to silencing effects.

Hunters

• Aspect of the Cheetah: Can now be learned at level 16.
• Deterrence now has a new visual spell effect.
• The time that traps will exist in the world after being put down has been reduced to 30 seconds, down from 1 minute.
• Traps now have separate 30-second cooldown categories: Fire (Immolation Trap, Explosive Trap and Black Arrow), Frost (Freezing Trap, Frost Trap) and Nature (Snake Trap). A hunter can have one trap of each category placed at one time.

Talents

Beast Mastery

• Catlike Reflexes now also reduces the cooldown of your Kill Command ability by 10/20/30 seconds.

Survival

• Entrapment: This talent no longer works with Immolation Trap or Explosive Trap.
• Lock and Load: Now has a 22-second cooldown. The Lock and Load effect cannot be obtained on targets immune to snare effects when Frost Trap is used.

Pets

• Roar of Sacrifice: Redesigned. This ability can now be used on any friendly target to make that target immune to critical strikes, but the hunter pet takes 20% of all damage taken by that friendly target. Cooldown increased to 2 minutes.

User Interface

• Macros and scripts will no longer be able to target totems by name.

Professions

• Alchemy
  • All stackable potions now stack to 20.
  • Added a new pattern for Flask of the North, usable by players with a high alchemy skill. The recipe is purchased from Northrend trainers. Flask of the North increases your spell power, attack power or Strength for 1 hour and is usable in arenas. It is not consumed when used.
  • Endless Healing Potion and Endless Mana Potion no longer usable in arenas. Amount of health and mana has been increased, and the cooldown reduced.
• Cooking
  • Blackened Dragonfin Recipe: Now only requires 1 Dragonfin Angelfish.
• Enchanting
  • Values on Northrend ring enchants increased.
• Engineering
  • The Ultrasafe Bullet Machine and Saronite Arrow Maker schematics have been simplified to create a full stack of the appropriate ammunition. No longer requires an anvil. Reduced the materials required to make this ammunition.
  • Potion Injectors now increase the amount gained by 25% when used by engineers. Quantity produced by recipes for Runic Healing and Mana Injectors has been increased.
• Herbalism
  • Increased healing from Lifeblood (Rank 6).
  • Lifeblood now scales slightly with maximum health. No longer affected by global cooldown.
• Jewelcrafting
  • Dragon’s Eye (http://www.wowhead.com/?item=36766 or http://www.wowhead.com/?item=42143 ) gems stat bonuses increased.
  • New recipes have been added for cutting epic gems and can be purchased using Dalaran Jewelcrafter’s tokens.

Bug Fixes

• Hunter
  • All ranks of Sonic Blast now properly have an 80 Focus cost.
  • Black Arrow Ranks 5 and 6 training costs have been lowered significantly.
  • Lock and Load: The tooltip for this talent has been updated to indicate that it also works with Explosive Trap.
  • The tooltip for Improved Tracking has been slightly re-written to indicate that it only works on the hunter, and works on melee damage as well.
  • T.N.T. (Rank 3): Now indicates that the talent works with Black Arrow.
