These changes were noted on the PTR:
- Slayer
- Overwhelmed now stacks up to 10 times (was 12).
- Culling Cyclone bonus Bladestorm damage reduced to 15% (was 20%).
- Opportunist now increases the damage and critical strike damage of your next Overpower or Raging Blow by 25% (was 30%).
The following changes were already made this Tuesday:
- Culling Cyclone bonus Bladestorm damage reduced to 10% (was 20%).
- Opportunist now increases the damage and critical strike damage of your next Overpower or Raging Blow by 20% (was 30%).
So is overwhelming blades still going down to 10 stacks? This would really not help the case for single target, even with the upcoming changes to raging blow and bloodthirst.
