Outside of a nuke and bomb catapult the blink is the only other real one shot weapon in the game. why is a one shot on the smallest and most fragile ship? why is it more powerful than a nuke? theres no reason for it. for a game based around slugging it out with large ships, one shotting in general isnt great idea. its why there are so few mods that can do it. corvettes can easily do enough damage up close that they dont need it.
as for the tacs negating damage, thats another balance issue. youre basically saying two wrongs make a right.
