Already looked into this myself, it can help you claim things, but not adequately defend with controlled will. It will make the defender more vulnerable to a persistent threat or especially coordinated threats. You will run out of hacking power and still get raided. The more land taken, the harder inherently it will be to defend, just an unavoidable reality of life itself. Which makes this game better.
In real life imbalances come at costs, unlike normal digital games OP can exist without much cost and therefore those games need effort to balance all the time. Real life takes care of itself. History provides plenty of examples.
