I'd agree. But Tier 5? No way. It would be on par with the Miranda and the TOS Enterprise, certainly.
It wouldn't even be tier 1. The TOS consitution class completely out matched it (as in it was taking out Fleets), in the mirror universe/time shift eposide.
The Miranda class is way more powerful than a pre-refit Consitution class, which was hugely more powerful than the NX. It would be like a 1970's hot rod, racing a model T.
It should not be in the game, in fact neither should the pre and post-refit Consitution class as it completely breaks canon. The only surviving Constitution class is the NCC-1701A (rebranded M), which is a museum piece. The NX has long gone.
The most sensible way to do this would be to add it as a skin for tier 3 escorts and up-refit versions of same, considering that (on the production side of things) the NX design was rehashed from the Akira to a positively absurd degree.
Yes I voted for it and would pay c-store cryptic points (aka cash) to have one, especially if it was upgradeable. I wouldn't mind using the c-store to buy ship parts so I can go to a shipyard and upgrade ANY ship to ANY tier and make it dependent on the number of points your willing to spend to get it there.

Essenctially all they did was rotate the pilons and retro its look. A simple fix is to simply turn your monitor upside down.
