Indeed...in Dark Heresy, of course you suck. You suck slightly less than the shmucks who weren't picked by an Inquisitor to be their lackeys, but you still suck. Rogue Traders are rich, so they can hire the people who suck even less than the Throne Acolytes (but they still suck, because they're humans in 40K). Space Marines hit things and kill them, and definitely do not suck...but you don't like Deathwatch because it involves hitting and killing things. Wut.
