Any chance the Romulan Scout Ship seen in "The Defector" will get added? It could serve as the tier 2 science ship. Then, the Science Ship seen in "The Next Phase" could be the tier three science ship.
I will add that I would like to see these added NOW as enemy ships for both Romulans and Remans. I have no doubt that Obisek has quite a few of them in his fleet.
