Over the past few weeks, we’ve updated our Balance Test Map with different changes aimed at addressing Terran and Zerg 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

• Removed Transformation Servos upgrade
• Changed Hellion/Hellbat transform requirement to Armory

Zerg

• Brood Lord gains the Frenzied ability
• Frenzied is changed to also be immune to movement altering abilities

If you're interested in the StarCraft II Balance Team's reasoning behind each change, you can check out David Kim's recent forum posts on both the Terran and Zerg changes.

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.
