Blizzard’s September 24 beta update changes the Warrior in six lines (a Sunder Armor threat fix, a Protection talent swap and four Arms changes) and adds one line for the Rogue and two for the Warlock.
Arms gets the numbers: 
Bloodthrill activates 4/8/12/16/20% of the time (was 2/4/6/8/10%) and only off Main Hand melee attacks, 
Cleave and 
Heroic Strike included; 
Slam has an 18 second cooldown (was 15) and Improved Slam now cuts it by 1.5/3 seconds (September 24 development notes). In the Protection tree, 
Bastion (Row 5) and 
Focused Rage (Row 6) swap places, which Blizzard’s note explains as giving Focused Rage sooner while leveling before 
Shield Slam, and 
Sunder Armor gets corrected threat values on every rank with a small increase to the threat from Attack Power. The Rogue line is a PvP flag fix for 
Sap; the Warlock lines are a 
Life Tap tooltip correction and the Voidwalker’s 
Sacrifice now scaling with 10% of the Warlock’s spell healing. When this post was written, our spell pages and the Warrior talent trees were on build 1.60.1.69913, and Bastion and Focused Rage still sat in their old rows and Improved Slam still showed its older effect there.
What to do: if you play Arms with Rend on the target, Bloodthrill’s Overpower activations now come only from Main Hand swings, Cleave and Heroic Strike, at double the old chance. Protection players find Focused Rage one row earlier in the beta tree. A Rogue who Saps a PvP-flagged target is now flagged too, and a Warlock can read the exact Life Tap conversion on its tooltip.
