As was @shootall mentioned, there's already a thread on this topic, albeit in a different subforum. In short, Uber knows and is working on it.
I also think fabricators are too expensive right now, given their low build power. Combat fabbers have more build power relative to their initial cost and are more efficient than regular fabbers. Part of the reason turrets seem UP in the PTE is because it requires more engineers and some early micro to set up effective defenses.
They are combat fabbers though. If they were as expensive, which even means if fabbers were cheaper, then fabbers would a lot of the time be used at the very least for turret repair. Combat fabbers either need efficiency reduction, or unable to assist. Possibly build for mines. But if they can't assist they don't really need to cost "energy" at all, and that would make them worthwhile (they don't tank your eco repairing)
