Easy thing to do is make a klingon character or even a new fed character and if you haven't played a certain class yet, like, say science, do that! Instant gameplay change. Should tide you over until the Oddysey comes out in the C-Store.
seeing that they have taken the "type ship skills" from the skills tree, does it really matter which version you use depending on the con slots you want? other than each version having its "special" ability that is.
