What do you think the point of high tech ships are?
Good ships — bad weapons. It's a matter of balance.
You cannot separate the value of a ship from performance of the ship hull and the weapons it can have; both are considered for a "good ship".

But AI is not good at exploiting speed. And suffers greatly whenever it is outranged. Even by ships it could actually crush at close range at some armor cost for approach.
Example: player piloted Conquest cautiously peeling a Grav+Autopulse Radiant, without ever raising own flux. If you do raise flux (by firing too much), AI will think it's time to attack and defeat you in close combat, where Radiant holds absolute advantage (and you won't be able to retreat because you need extra time to fully reverse speed vector). But if you cushion initial rush by backpedaling and never allow Radiant to fully disengage/drop flux levels, Conquest can win.
AI Medusa needs to go SO + Aggressive to win 1v1 against a Hammerhead (that uses a normal fleet-optimized non-SO, no-missiles build). Not a guarantee even then.
Didn't we all had this conversation before and it did turn out that an AI non-SO Medusa can beat an AI Hammerhead 1v1? It was just that you never gave your Medusa enough caps. I'll have to see if I can find the thread. Edit: I was wrong it was with SO.
Edit2: No loadout design skill, so 95 OP with 70% CR Medusa.

I see Heavy Mortars miss destroyer hulls regularily. Especially when shields are off. When shields are down, you want to hit the hull for obvious reasons. Cruisers are usually fat and slow enough to be hit with shields down, but even so the travel time and accuracy is excrutiating to watch. That said I do use heavy mortars but only becuase they fill the need in a reasonable range and available HE source for medium mounts. Accuracy does matter for smaller targets. For the most part it doesn't matter too much what the flux efficiency of an individual weapon is as long as the ship hull itself has enough flux dissipation. Taking ship hulls into account I consider the "pulse lasers" to be anti-armour inefficient not anti-shield inefficient, but then there are many high damage energy weapons that do well against armour, so energy weapon mounts have options for both.
