Actually it's the furthest thing from communism; it provides a more authentic free enterprise situation.
By no means am I saying there shouldn't be a progression system, just not one centered around stats that mean very little; being too relative in level and power rather than what I propose: stats being more absolute - therefore gauged more consistenly by the player, thus zones and creatures deliver a better, more accurate, representation of the content - mechanically.
The classical MMO template is much more communistic than a, static system. Marketers will probably tell you that demographics indicate people like bigger, relative numbers, and like to be led to and through content.
Hmmmm... if you prescribe that people should be led, that everyone likes progressively bigger numbers - that ignore an absolute ontic referent and that's just the way to have fun ... then what does that sound like? Authoritarianisitic Relativism - (coined myself and not really that appropriate but whatever)
