So while I'm waiting for this final splatbook (Phil will give up hope when his soul rots in the warp) can anyone point me to a good set of fan rules for a dvanced specialities for the Commissar, Stormtrooper and Psyker?

One of my friends pointed out this thread:

as much as i am with everyone else on this, you honestly have a better chance on making a petition that FFG will actualy listen to through Change.org
