Yeah, for my B5 ship write-ups I've kept it simple with regards to Missiles. They are just RKA's with a delay rather than vehicles. Besides, this way they could be applied to any incoming fire, not just missiles.
I'm a little zoned right now, but one thing I just thought of would be to add a limitation: Requires Abort to Dodge action; meaning you could not use chaff & flares unless you could abort to a Dodge or Dive for Cover Maneuver. Certainly in keeping with the spirit of chaff/flare use. Thoughts?
