I look at it more as playing a primary faction as opposed to a Master. When I started, I just had Seamus and a handful of Rotten Belles. Then I came to learn that this crew isn't very good at some things, but I still liked the game so I started to look at other models in the faction. Then with the discovery of Punk Zombies, I was able to add what my crew was missing - - some melee punch.
The Punk Zombie may "go with" Nicodem, but it turns out that with the way that I play, they also go with Seamus.
Try and hang in there and see if there are any models in Neverborn you think would be fun. The Spawn Mother (wave 2) can keep making babies for you, and I believe they are hard to shoot. The babies also have a chance to grow up to be Silurids.
Aslo, Ortegas (and Kin) might be the killiest crews in the game. They are also pretty straight forward, easy to use, and forgiving of mistakes. Perdita = Easy mode while Lynch isn't.
