If anything should be 2.5 it should be the Excalibur. Its an updated version of the Connie, so it shouldnt be "equal" to TMP connie like it currently is in game. T3 might even be more appropriate.
Indeed. That could actually work. As the Excalibur is technically a updated 2409 Constitution class anyway. I've always seen the Excalibur class to STO like the Enterprie is to any of the films and series. I think it is because she's on the front of the box (special edition and normal US copy), and everywhere I would see an article on the net or in a magazine I always saw the Excalibur class.
