On the other hand, some people are creating really good maps that are fun to play and look and feel like a product rather than an exercise in editor.
Therefore it is a big news that Blizzard has published this custom map. The map is taking the idea from Devil's Playground mission and bringing it up to a multiplayer level. Here is official description:
Featuring timed lava surges and collectable mineral caches, Burning Tide is a 3v3 map that combines several thematic elements from the epic single-player campaign mission "Devil's Playground." Like the campaign mission, the goal of this game is greed, and the first team to reach the specified resource total wins! Players hoping to achieve victory on this map will need to work together, carefully managing their team's unit production and safeguarding their vulnerable workers as they defend against enemy forces.
Here is how it looks.
I haven't played it yet but it obviously takes resource collection strategy to a new level. Workforce generation and it's protection is a key for this map. Air force seems like a key player...
