For all intents and purposes, the Guramba is our 'Nausicaan escort', as it functions like a raptor/escort when not in siege mode. If they were to add another ship, it'd be something like a carrier or a battlecruiser.
But the Nausicaan escort is a nice design. I can see it coming in game as somekind of a "glass cannon" maybe to counter the Kumari on some level. But the question is wheather Cryptic sees it like that.
Because true Starfleet Captains command Exploration Cruisers!
Thank you Cryptic for finally giving me MY SHIP!!!
