This is one reason why you can mount the gun frigate - gives people a taste of how they think, if they like 'body, they can go to defend levels(STO Powerleveling). Since you only get one free, each class of ships, according to what you want, they have to ship to a different energy credits fork over.

You see, T1 (or you call it, T0's) objective is to absolutely nothing for people to know how the game is played - is a generalist in the layer to the ship design, because people do not know how to play what they want, as a flying boat class. You start to specialize in T2, when you have a grasp of the game(star trek gold), and you want to do with a vague idea.

And when you are about to open, energy credits can be hard to come by Star Trek Online. Now you can see what you have disadvantages? Also little change in the T1 to the design - noobies no knowledge, so choose what you want. Both sides of the post, because your purpose is, you want Akula-class (this is the brave, if you really want that little configuration you can go to the Cheyenne-class in T2), they will be better off placed in Challenger level, but not - at least it is Canon.
