No, the answer is that different classes have different requirements.The answer is None. So we are arbitrarily punishing some classes and not others.
You want to revamp the classes so that every fighter is a vassal for his Lord, every rogue gives a cut to the local thieves guild, or every bard is under contract from her manager, I'll buy the whole God micromanaging clerics and warlocks forced to serve their patron.
Lords, thieves guilds, and managers are not the same as gods They are not equivalent.
And I have played games where rogues had obligations to the local thieves guild, and fighters to their Lords.
