I do think it'd be a good idea to basically go through all the rules for each server and talk them over or at the least clean them up and make one big list that's up to date and has any unsaid rules or conditions for certain rules. Would also help to make some stuff less up to staff discretion or subjective since then you'd get less issues where someone does something because they thought it was allowed, but then another staff punishes them for it.
Not to say every staff is doing things wrong or such mind you, but it'd help if everyone had similar goals or rules in mind.
