This is unusual/interesting because since a few years StarCraft II is in zombie mode, and Blizzard has skipped a few balance patches and changes in the map pool, and is not producing new content to sell in game.

So perhaps this means that SC2 will become less zombie or at least not become full dead soon.

This video by Harstem sounds like Blizzard set up a community working group that can and will coordinate future balance patches. Great sign indeed.

They need to nerf widow mine splash damage.

The Queen nerf will impact early queen walks (good).

The Void Ray changes are not good.
