It's not that anything is wrong with it, it's just that a Galaxy X will lose to a Sovereign 75% of the time, lose to a Galaxy Retrofit 80% of the time. (taking DPS, tanking abilities, speed and turn rate into account)
IF I spend any cash on a ship, I want it to be one I can use effectively at the level cap. It's okay; but there are better options (both play-wise and aesthetically) for free.
EDIT: Also congrats on reaching 1900 posts! 100 more to the next magic mark!
