1. Assuming a Hard TEC is not able to blow apart your poorly arranged Static Defenses (Even though TEC isn't that good), what are you supposed to do then? He easily decimates your trade ports and your income and your stock market crash, what's next? Build a fleet of Light Frigs and charge into battle?
2. Discpline fleet against a Hard TEC? They will get shredded, as the user aboev me posted, by LRM's, and once your "fleet" is gone and your economy is in shambles, and your poor planetary defenses are being torn apart, there is nothing to do but surrender or fight with what you have left (Basically a few thousand credits and a couple poorly-defended planets with the largest space fleet in history assembled right on your doorstep).
3. Undying horde? The enemy is the undying Horde! You have shit while you wasted thousands of credits, metal and crystal on hangars and turrets, while you didn't do shit to scout the neabry systems, and the enemy is slowly buildign a fleet of massive capital ships with names like "n00b pwnzrz" and "ul71m4 h4xx0rzz".
There's some comments for you.
