This is one of those cards that FFG seems to have been too conservative with, it has this needless large ship only restriction on it.
Most small bases want Autothrusters or in case of Vader or Corran, Engine Upgrade. Miranda wants Advanced SLAM, Phantom wants ACD. TIE/SF's want Lightweight.
What small bases would countermeasures even be good on? Omega Leader I suppose, when being shot by multiple targets and to ditch a TL from something that can modify its dice. What else?
Interceptors maybe? They'll always want Autothrusters, but their second mod slot is usually up for grabs.
Sycks? With Mindlink and Countermeasures they could have 4+ agility, focus, evade and 4 health. That's not shabby. Countermeasures could be a way to soften the fact that Serrisu's ability doesn't work on herself.
