Yeah, in retrospect, it must suck to have your life determined by your blessing.
The sage has the compulsion to be the smartest guy in the room, so he inevitably has an easily wounded ego and mostly book-smarts.
The guide has to be the one to support others, so he inevitably has to put others before himself and help them get past personal hurdles.
The hero has to fight for the greater good, so she isn't allowed to kill the stupid bastard that drove the person she cares about away.
