Skills
Combat

• Gouge awards one combo point once again. (as it should)
  

Subtlety

• Tricks of the Trade now costs 15 energy. (for a skill with a 30s cooldown, this doesn't make sense)
  

Talent
Assassination

• Hunger for Blood now only attempt to remove a Bleed effect. (Old - any harmful physical effect) (removes pretty much all PvP use)
  
• Deadly Brew now only has a chance to apply Crippling poison (plain and simple nerf to an overpowered skill)
  
• Improved Poisons now increases the chance to apply Instant and Deadly poison to your target by 2/4/6/8/10% (Down from 3/6/9/12/15%) (this is taking it a bit too far)
  

Combat

• Savage Combat now also increases your total attack power by 2/4%. (good DPS builder)
  
• Vitality has been changed now increases your Energy renegeration rate by 3/6/10%. (does this synergy with Combat Potency?)
  
• Aggression has been moved from Tier 6 to Tier 5 and changed to 5 points. Now Increases the damage of your Sinister Strike, Backstab, and Eviscerate abilities by 2/4/6/8/10%. (I don't think they understand Combat builds with this change...)
  
• Endurance now increases your total stamina by 2/4% additionally from the Sprint / Evasion cooldown reduction (4% isn't much but it does make this filler talent better)
  

Subtlety

• Filthy Tricks now the cooldown of your Tricks of the Trade and Distract abilities by 5/10 secs and Preparation by 2.5/5 min. (ehh...)
  

This is a very odd push, with some significant reduction in DPS on the assassination tree, to the point where there seems to be no benefit of going Mutilate anymore. It's a real head scratcher.
