I have always been tempted by the little guys But i ended up getting Viks crew when i started and recently got the rail crew box set and "WILLIE"!!!!!!! (I feel the need to shout his name in a Scottish accent, No idea why though. I may do that each time he activates until it annoys my opponents).
I'm sure i will end up getting a Gremlin crew, especially if they bring out that guy from the wallpaper pic a while ago. the multi-barreled weapon guy.
my army/crew selections have always been on what i like the looks of, screw the rules I'll deal with it. I ended up settling on Viks as with other crews I'd like the looks of a master but hate the other models, or love crew hate the masters etc.
