Yeah, fiddling with the launchers is my next step, followed by cleaning up the torso. (My removal of the -XR's laser was pretty messy, those panel lines are a total loss at my skill level.)
One thing I've decided is that I'm NOT going to drill out extra missile tubes to match the stats, at least not in the arm launchers. Drilling out all those holes would be a huge pain, there's no way I'd be able to make them consistent across all eight racks, and I don't think there's actually room for five more tubes on those pieces anyway. If anyone asks, I'll just say the Kraken uses technologies derived from the Atlas's fast-firing launcher. They're not *as* fast, but they can manage an average of fifteen missiles per ten tubes per ten seconds.
