A little while back, we requested your help in testing a few proposed balance tweaks for StarCraft II: Heart of the Swarm by playing with each change on the Balance Test Map. After reviewing your thoughts, gathering pro player feedback, examining ladder stats, and watching lots of tournament matches, we're ready to move forward with a balance update.

Today, we’ve implemented the following balance changes for StarCraft II: Heart of the Swarm multiplayer:

Terran

• Hellbat
  • Attack damage decreased from 18 + 12 vs. light to 18.
  • The Infernal Pre-Igniter upgrade now increases attack damage to 18 + 12 vs. light.
• Banshee
  • Cloaking research cost decreased from 200/200 to 100/100.

If you'd like to read more on the reasoning behind these changes, feel free to check out David Kim's recent forum post, in which he provided his team's thoughts on StarCraft II balance after reviewing test map results and feedback.

As always, thank you for play testing the changes we proposed with the most recent Balance Test Map. The extensive testing and quality of feedback you've provided have allowed us to make this call, and we look forward to sharing more of our thoughts on StarCraft II balance with you in the future.
