Over the past few weeks, we’ve updated our Balance Test Map with different changes aimed at addressing Terran and Protoss balance concerns. After gathering and reviewing feedback on these changes, we’re ready to move forward with a new balance update. You can expect to see the following adjustments applied to Heart of the Swarm multiplayer today.

Terran

• Widow Mine
  • Splash radius is now 1.75. There are no longer 50% or 25% damage zones.
  • Splash damage is now 40 (+40 Shields) for the full 1.75 splash radius.
• Thor
  • Changed to prioritize their AA weapon over the AG weapon

Protoss

• Mothership Core
  • Time Warp duration decreased from 30 to 10 seconds

If you're interested in the StarCraft II Balance Team's reasoning behind each change, you can check out David Kim's recent forum post on the changes. Along with the balance changes, we've also made some changes to a few ladder maps. You can check out the details on those changes here.

Thank you very much for all of your feedback on the proposed balance changes. Your thoughts and playtesting helped shape this update, and we hope you’ll continue to participate in future balance testing.
