Right - which just switches the question to "what do we mean by "archetype"?"At the risk of stating the obvious, classes are for allowing players to play an archtype with a balanced and fun set of appropriate abilities. There are interesting arguments to be had about how broad/flexible classes should be and whether the archtypes overlap (e.g. paladins and melee-clerics), but that's what they are for.
Is an archetype just an aesthetic, look-and-feel thing in the game world? Or does it have some role in resolution or capability of the characters in-game? Does it have any defined limits? Or is it just a seed of inspiration?
