After soooo many people use the Rupturebeam on their Annihilators (actually i never(!) encountered even one because of its overwhelming range and the sheer fact that beams on Battleships suck you make theexact same mistake again.
Another Battleshipweapon that wont ever be used on a battleshipbecause it is completely unusuable for this shiptype. Its an ice Kutter or Cruiserweapon, but not for Battleships.
Whatwas the design idea behind such a short ranged weapon? Did you forget that Battleships actually get a rangebonus and are used by virtually everyone as a sniping/kiting platform?
