I've been tinkering with Jess/Low without Biggs/Rex. That list is all about damage distribution. What if you had most of that damage distribution, but with theoretically increased offense output and/or control? How would these lists suffer where Biggs/Rex would succeed? I've run the Norra and Miranda versions and they won, no ship died, so they're at least not terrible.
