With Piett's ability (effectively) confirmed, what's his niche? He seems like a good fit for:
1. The SSD, obviously. Double super commands on the centerpiece of your fleet? Yes please.
2. Thrawn 2 ship. 6 points cheaper, works every round, slicerproof. The downsides being he only affects one ship and you need a token (Wulff/Hondo/Vet Captain?) Not necessarily better than Thrawn, but there definitely seems to be a place for him there.
3. More generally, a carrier battleship list centered around an ISD, which can throw squads and do something else.
4. Someone mentioned the Interdictor, which can refresh him and makes a good flagship.
So what are your plans for him?
