The big news in general is all PvP: Random battleground system (like the random dungeon system); battleground Marks removed.
There are also some interesting changes to the UI for the auction house and the quest tracker.
And here's a round-up of the hunter stuff:
- Hunter Talents
- Beast Mastery - Ferocious Inspiration: This ability is now an aura and provides 1/2/3% damage to all party or raid members within 100 yards and boosts the damage of Steady Shot by 3/6/9%.
- Pet Talents
- Heart of the Phoenix: Cooldown reduced to 8 minutes, down from 10 minutes.
- Hunter Bugs
- Explosive Trap: Low ranks of this ability were receiving no bonus damage from attack power. That has been corrected.
- Immolation Trap: Tooltips for lower ranks should now display more accurate damage.
- Rapid Fire: Now triggers the global cooldown correctly.
- Sniper Training: Reduced the time it takes to gain this effect so with lag it will feel more consistent with the 6 seconds stated in the tooltip.
- Lock and Load: Fixed a bug where Lock and Load always proc'd 100% of the time from the first tick of Explosive Trap and never from additional ticks. It should now be 6% as advertised.
- Master's Call: This ability will now function correctly when the pet is affected by one of a death knight's diseases.
- Mortal Shots: This talent was not correctly buffing Serpent Sting by the full amount.
- Pet Bugs
- Glyphs which modify a pet's stats in any way will now force a recalculation of the pet's stats when they are equipped or unequipped.
