, I hope you realize that in this and your other thread, the stats are, at best, vaguely based off back-stage info, which are merely one
Really, what are you expecting? From any set of base assumptions you can come up with anything. For example, I don't believe the Sovereign is anything particularly special or "war-like", or that the quantum torpedo is anything particularly special, etc., etc., etc..
Even if the Sovereign has sparkling new fancy junk, it goes without saying that newer ships tend to get newer things faster, because older ships have to wait for their next refit. (Which also makes for interesting situations where older ships fresh out of refit are actually "newer" than newer ships.)
