If work gives me a break (small hope), wil try the 'reduced cripple' option for the Gorn - can't see the pionts dropping by more than 1
 The following is a possible list of altered stats for these ships (class - current - altered values)
  DD - 16/6 - 16/5 (-1)
  BDD - 16/6 - 16/5 (-1)
  HDD - 24/8 - 24/6 (-2)
  CL - 24/8 - 24/6 (-2)
  BC - 32/11 - 32/8 (-3)
  BCF - 32/11 - 32/8 (-3, had thought about -2 as the ship 'might' be structurally effected by it's turn of speed, it's a fast, lumbering ship after all. Sticking with basic idea)
  CM - 32/11 - 32/8 (-3)
  BCH - 32/11 - 32/8 (-3)
  DN - 52/18 - 52/14 (-4, thought about -5, but will stick to the pattern that has shown itself - crippled rating of lower class, which reduces stats by 1 per class.)
  Nothing to great, and nothing across any ship that a Photon Torpedo won't counter. Most ships will remain slightly more combat effective, but  not to a great extent.
