My crews are:
Ramos
Colette
Raputina
Hoffman
Crid
Perdita
Justice
Lucius
Kiria
Von Schill
The Viki's
Hamlin
With Karis due in Thursday.
I've used Hoffman, Ramos, and Rasputina the most but still haven't played The Viki's, Hamlin, and Kirai as I just got them in a trade.
I really don't have a favorite individual model to play though the Mobile toolkit sees the most use with both Ramos and the Hoff.
