Yep, that would be the Cruiser
Escort for tactical and well, Science for science.
I would suggest you try all three ship types (energy credits are easy to come by and there is nothing else to spend them on) - you don't have to stay in the "set ship". Actually, some builds work well outside the designed ship e.g. an escort will survive longer with an Engineer captain, but will still give more of a punch than a cruiser. Of course, I have been out of the loop for a while, so things may have changed!
I don't get why this game hasn't had any updated reviews. It is much better now. I remember GameSpy_Ryan telling me -
"This may come as a surprise, but we reviewed the game as it actually exists -- not based on nonexistent content that may one day be patched in. Seriously, I don't get all the MMO apologists who defend bad launches and poorly plotted leveling flow. The "we'll patch it in later" school of design has been prevalent since the early days of MMOs, and genre enthusiasts are so beaten down that they just accept it because that's the way it's always been. This is not a good practice, and people need to expect more from their games."
Then why not post an updated review later on? Of course, I always enjoyed that comment coming from the people who gave:
AoC: 4 Stars - "GREAT!!"
Warhammer Online: 5 Stars - "OUTSTANDING!!!"
Tabula Rasa: 4 Stars - "GREAT!!!!"
