Is it good the Imperials get to have some fun with a Huge ship .... Yes
Have they been waiting long enough after Tantive & Transport .... Yes
Is it cool it Kinda looks like a Star Destoyer ... Yes of course
So just curious .. why design a whole new ship unseen and unsed in core or expanded universe, when you could just use the Imperial Interdictor vessel that is already established?
Much smaller than a SD .... its Mass Generators could have affected Movement of vessels etc.
just seems a lot of effort when a ship already fits what was needed?
