As much as I liked the idea of features, they were so utterly varied in usefulness and power that they were a nightmare. So easy for the player and the referee to have wildly differing ideas of what they mean and how they're supposed to play out. Like noble. A lot of players seem to want it to be a universal mind control of peasants. A lot of referees simply banned it in response. Or the acolyte's free healing at a temple associated with your deity. Or the hermit's discovery. Or the outlander's free food. Neat idea, terrible implementation.
