Yep the intersection of the scales is definitely the main pain point in the Star Wars rules and the main improvement of the Genesys ones. I've considered figuring out a simpler port just for those situations, but haven't had a game that needed it enough yet. And of course if you're working from a data set you can manipulate all at once that's fairly clean too.
Their rules have a fair bit of overhead per ship. If you're using a lot of the same stuff it's not bad and the Genesys rules are better, but I value being able to improvise encounters a bit too much to use it personally.
