Hm. I know my opinion will be kinda unpopular, but still. It's not about the models, it's about skill. FC is 3 and 2. 13 wounds are not much compared to gremlin damage. HtW is easily avoided by focusing. You can control FCs with Sammy, you can burn the hell out of them with Merris + Ophelia's hooch igniter(Burning not only them, but everyone around. You can place ALOT of burning this way. Like 6 burning from Ophelia, to a target and anyone up to 6" away from target. Merris can place even more). You literally can do anithing with them. With careful placement and The Kin's new mobility tricks - FCs are not scary at all. Ophelia can kill FC at ease with her pluses and stones, stilted Franc have minimum dmg of 12(per activation) w dumb luck, and can act immidiatly after Ophelia. If you want to buy new models - Burt and Gracie are always bold choise. If you want to play only against ressers - buy Wong, Burt, SwineCursed, Old Cranky and Sammy. That would be more than enough. You don't even need Mancha(Insta gib trick is good, tho).
Sammy with "Ooo Glowy", Burt With magical and DC, Cranky, 2 Swine Cursed and 1-2 Bugs.
Wong loooooves low df enemy models. And with his ca7, if enemy takes 2 flesh construct from the begining and fail with deployment - Wong can wipe half of an enemy crew with blasts and pulses at the start of turn 2.
I did this alot of times. 2 low def models(htw is pain, tho) in enemy crew is an opportunity to use Lightning Jump alot of times in single activation, blasting and pulsing everyone near low df models.
Sorry for my broken english.
