Although the Zerg had enjoyed a tremendous intelligence advantage early on thanks to their unique technological path, their wars with the Star Sea Alliance and the Epoch Clan had already been going on for nearly three hundred years. Much of their data had been uncovered or inferred.
This included the maximum rate at which the Zerg could mass-produce troops in each star system. To produce troops at maximum capacity, their combat units had to mature in close orbit around a star.
And such an exposed environment near a star was easily observed. With the Epoch Clan's level of technology, they could even observe it from dozens of light-years away.
Thus, based on estimates by the Epoch Clan and the other races, every Zerg Star Gate could support two to three star systems producing troops at maximum capacity.
Although Zerg territory had expanded dramatically, most of it consisted of newly occupied regions still focused on mining resources and establishing bases. They were nowhere near capable of producing troops at maximum capacity.
There were currently nearly three thousand Star Gates within Zerg territory, and their existing holdings simply could not sustain full-capacity operation. Splitting their current forces might have been viable before, but the Epoch Clan had now undergone a massive upgrade, multiplying their troop production speed several times over. If the Zerg split their forces now, they would only be asking for trouble. A shortage of troops could very likely lead to a disastrous defeat on the main battlefield.
This wave of Star Gates the Zerg were building across various star regions would likely exceed ten thousand in number. Expending such immense resources to construct so many Megastructures with virtually no combat capability—wasn't that just giving away resources?
But the Zerg were no idiots. They would never do something so brainless.
