It would involve a change of how we assign mentor points, and who can be awarded them. If there is no class, and no other distinguishing feature that would make a character rightfully gain mentor points, then there is nothing stopping just about anyone from getting them. But then what is the point of those mentor points if not to reward those who put in the effort? Of course some rare students are jerks/don't care enough and give low marks for no good reason anyway.
