Hello, just wanted to post this here.
I expect everyone in these forums has already seen this article on TL, but I figure any extra visibility is a good thing.
The wonderful article essentially provides an in depth and elegant solution to the restriciveness of the SC2 economy. In short, it suggests a slightly changed mineral collection mechanic which provides greater benefits to expanding while not forcing expansions as quickly as the LoTV beta economy. This change would ultimately add more strategic depth to a greater number of playstyles. Hopefully more exciting and diverse games would come of it.
Definitely worth a read!
