I do not see the problem with you starting out with a small ship. You do not start out with the official rank of captain. You are called "Captain" because that is the standard title of anyone in charge of a ship. You will have to advance in rank and skill to command different ships. You do get to choose a particular area other than command like science, medical, engineering, etc... The thing that I find interesting is the bridge crew and the ability to recruit them and train them. I honestly thought Star Trek Online would never see the light of day but the screenshots that Cryptic Studios have shown look promising and there will be a closed beta in october.
