So, after 60+ pages of threads we get to the point that ‘roles’ are just a bit of jargon? A point of pure semantics to argue about? Agreed.
Pretty much. It's a lot of debate over semantics. Classes clearly have different strengths and weaknesses, obviously, and everything after that is a desire to label and categorize but it's not necessary to label or categorize in order to express those strengths. The strengths exist regardless and that's what we often term when we define roles. If a new player asked me about a class because of unfamiliarity I could explain them easily enough.
