@Thane It's not that the hero can't be good...and since it's modeled (tau flavored) after the lunar, it seems strange that it is both harder to destroy and pack more firepower in every single arc than a lunar (it has 2 less battery on a side facing, but also has 2 launch bays to throw in; 1 launch bay = 3+battery FP). It literally has no weakness over a lunar. The only possible scenario that the lunar could prove more useful would be firing at three separate targets in 30cm. The Lunar would win out, but this scenario seems rather rare without special order usage (in which case the lunar is on par again or slightly worse). And the Hero is more resilient too, having an extra turret and more defensive ordnance.
The Hero also has the same role as the lunar; line battle ship of its fleet. It just happens to have strong combined ordnance to go with it. It just irks me that it's either not more expensive or less powerful.
