oh man, too tough to call.
i'd start by saying that the guild is the one that interest me the less (tough the ortegas are starting to grow on me).
I don't have much interest for the outcast except for the gremlins. I'll probably use the others once in a while as mercenaries , but I don't plan on buying a whole faction of them.
For the arcanist, I really really like the steamborg, hopefully the other classes will be as cool as him. Marcus crew is also one of my favorite, every single models in it is insane. Hopefully we'll see the rules for the cerberus soon. I have zero interest in rasputina and her crew.
In the ressurectionist, I really dig mcmourning. He loos like the crazy orthopedist in the video game vampire the masquerade (best video game sequence ever). His miniature, tough simple ,is one of the greates i've ever seen. Really catch the craziness of the character . I'm eager to see the other construct he will have. Mad hatter crew his mad cool also (the belle are gorgeous). Not too much interest in nicodem
Among the neverborn, Pandora is the one that interess me the less, while Zoraida is among my three favorite master. I like the way she plays ( in other mini games I play, i usually likes to play factions that put hex and curse on the ennemy). Her totem (the vodoo doll) also seem really fun to play with (and I'm pretty sure the mini will be magnificient). As for Lilith, i like her, but perhaps not enough to make a crew out of her (unless I really like the way she plays).
So finally, Id say it's a stalemate between Ramos, Marcus, Zoraida and mcmournning. I'll probably make my choice depending on the factions of the persons i play with
