GiantBomb interviewed Dustin Browder at the studios recently to discuss race balance, whether there are units that will be removed or not. The developers are seeing several game situations, things they didn’t foresee players coming up with like a Queen rush on Protoss players who aren’t effective that early at blocking chokepoints and protecting the base. The Queen’s speed will be nerfed to prevent Queen rush.
Dustin also talks about the single player’s Challenge mode.
