I’m not sure about Old Teroch or Fenn Ray, but with the reduction of the generics, the I4s need reduction as well. Kad Solus probably isn’t 7 points more effective, and no way is Joy Rekoff worth even a point more.
In fact, Joy should probably cost a point less. That would be fine, since you can only take one of her, and she’d be 5 points more expensive if she had a pilot ability anyway. The discount would essentially be her pilot ability in this case.
