I've had trouble getting 60-100 point holes in an Imperial list filled, something that is easy to fill in Rebel lists with CR90s and Hammerheads. Those ships are cheap and effective, and don't really care about who is the Commander. Now don't get me wrong I do like Arquitens and Raiders, but when I use them in a fleet I typically build around them, rather than as an effective points filler.
Should the Empire in your opinion get a CR90/Hammerhead equivalent, and what ship(s) get your vote to fill that niche?
It might be passed over by FFG for too derivative of the CR90, but I think the CR92a is a cool example of the Imperials learning from Rebel successes.
