On May 10 in US and May 11 in EU, after a brief maintenance period in each region, the following balance changes will take effect globally:


Protoss
* Observer build time decreased from 40 to 30 seconds

Zerg
* Overlord movement speed increased from 0.4687 to 0.586, that is 25% faster
* Queen anti-ground weapon attack range increased from 3 to 5

Terran
* Bunker is not changed


Again, to be clear, these changes will take effect after a short maintenance in each region is complete, and neither a patch nor any other special action will be required to experience them in-game.

Thank you for your feedback, and see you on the ladder.
