If you can seriously look at ship A, which is devoting half of its capacity just to not fall flat on its face when it tries to fire its weapons, and compare it to ship B which plugs in a set of weapons and sets power to maximum and then never worries about it ever again, and not realize that this is a serious gameplay balance problem, then I don't even know how to talk to you. It's like trying to explain the principles of mathematics to somebody who thinks the counting numbers are one, two, purple, dog, squish.
That's nonsense. That Escort has all it's tac slots filled with: APO, CSW/CRF, TT & THY/TS
Most likely it also has EP2W & A2B.
This leaves Hazard Emitters and Transfer Shield Strength or whatever for Science slots.
What you say is true for every ship. There is some build to optimize damage.
