You are supposed to be at the very basic premise of these games, a hero, you are not supposed to be following the same rules that normal people do, you are supposed to be above normal in every shape and form, this is not supposed to be a realistic representation of the struggles a normal person experiences in said game universe. So why struggle with rules that allow you to be a hero? rules that follow the very basic premise of any RPG.
In the 1st edition of Dark Heresy, you were supposed to be following the same rules that normal people do, you were supposed to be normal in every shape and form, it was supposed to be a realistic representation of the struggles a normal person with an extraordinary calling in said game universe.
Sorry to c&p but phone.
Anyway, you're completely right about DH2e and most (but not all) rpgs. It's the primary reason I don't play those games. When I want superheroes (by whatever name), I play the GW wargames.
Tastes differ & stuff. What you want isn't wrong. But I wish you wouldn't ask for it in one of the few games that cater to me. Because what I want isn't wrong either.
