Do you think giving the censors the power to rank and re-rank citizens into different classes was a good idea?

No I do not think it was a good idea. Lets assume you're talking about the period of Ancient Rome, it was commonly not a great idea for the censors to rank and re-rank citizens into mixed classes because it produced hostility between the groups, which led to national upheavals and chaos. 

Hope I helped. uwu
