I am sorry for putting it so harsh, but Shock Rays are failure of those who developed them. As well as Zappers. These guns can barely hit standing on one place cruiser. You have to turn not the turret, but ship itself to hit something with them. And considering that they're meant to be anti small crafts, I can not even imagine what do you have to do to make them work.
And also, they're shooting when they're active. Like someone pressed "Fire Forward" button. So on, let's say, carrier that have around 20 secondary turrets they will all shoot, just in front of themselfs... Even if target in exactly oposite dirrection. So even if one of them hit the target once, do you imagine how much energy battleship will be loosing to deal that small damage?
If the point of those turrets was to nerf cap ship abilities, then, "honorable" dev and balance team, you have to do the same to other turrets. If no, however, then just return old razors, because they're perfectly balanced against other ships.
