Where would be a good place to go for sources on ships/ship power then? I tend to use Wook quite a bit to compare ships. And if that's the case, maybe the Mk I could be upgraded to be more of a fast brawler. I mean, that's another thing, I'm a huge fan of the Dreadnaught, both Victory SDs, and the Vindicator. Let's just say I use the boarding party ability a ton. Hearing all this is definitely enlightening about the Mk I, and I'm becoming a bigger fan of it, now my suggestion would be to up the ante on it, instead of it being an anti-starfighter/anti-frigate ship.
It's perfectly fine to use Wook, most of us do, as long as you stay critical and keep in mind that it's the sources that count. And of course, now that most sources are legends you can pick and choose what you want to fit your personal canon. I tend to value how a ship's abilities were thought to be by the author that designed them and/or how they appear in the movies/novels the first time we see them. For example, the K-Wing never had turreted lasers when it first appeared and I'm fine with that since I prefer it as an Early Cold War nuclear bomber-type that relies on outflying enemy interceptors on its way to hit the target. Similarly most later sources keep telling us about how the Y-Wing is slow and rugged, yet that doesn't match their original design as a bomber stripped-down to maximise speed or their performance in the movies (in ANH Y-Wings are not rugged but fragile, in RotJ we see Y-Wings casually vaping TIEs and then flying inside the DSII superstructure alongside A- and X-Wings, chased by TIE Interceptors)
