Unless the alliance has something bigger I can see Fighter 5, Command 4, Engineering 4 for this thing. Maybe 5/4/2 shield arcs. But such a beast might be prohibitively expensive in 400 point games... would be like trying to cram an ISD into a 300 point match. It would somehow need to make the best use of its fighters as that's the only kind of escort it's going to get.
I fail to be excited about a ship that in the movie looks like simply yet another Star Destroyer. You probably need to compare with the shooting angle of earlier movies to notice a size difference. If at all.
Hence I am totally indifferent to see it in Armada. Doesnt fill any niche.
I like the hull underbite, the melded command tower, and some of the subtle differences. But I'm the kind of fan who gets excited over the slight detail differences of the Devastator model from A New Hope and appreciate it for its rarity (since the ISD-II Avenger , and the ISD-I mod into Avenger, are far more common).
