Ah, that D'deridex.

Rule number one, you're Klingon, act like it and use your cloak if you can.

Rule number two, always attack the sides.

Rule number three, have Fire at Will (beams) or Scatter Volley (cannons) ready to go. Those heavy plasma torps can be shot down if you have enough time to do it. If you want to spend EC, KDF can buy a point defense console that destroys heavy plasma torps, fighters, etc when you activate it. Search the Exchange for Console Pack - Subspace Jump / Point Defence (KDF get the point defense, Feds get the Subspace Jump, while Feds get the point defense from the C-store ship, and same with KDF and subspace jumper ). Looks like they are going for about 3.2 million at the moment.

Also of use, jam sensors, scramble sensors, Grav Well.

Sorry for the data dump, I've been on a more than usual STO kick.
