As it currently stand, BCL push timing is 2-3min behind every time. I’ve really tried to make up for it, but short of making a mass amount of Mecha Zerglings you can’t close the gap (based on maps/composition). And when you do, it’s technically the mass ling that’s doing the work versus the BCLs.
They need to address the cost as well as time barriers with BCLs
Here’s to hoping.
