Warhammer Fantasy Roleplaying is unique in that it acknowledge the differences between characters, classes (careers) and races. It also assumes that everyone rolls their races and careers, so more powerful options happen far less. In practice, many groups ignore that and just pick their race-career options.
There are good reasons for having classes and races be balanced (to a certain degree) in most TTRPGs. Any kind of narrative dissonance that this may cause is often an issue of the writing and lore, if there is any in the first place.
