Yeah but isn't 40-50 only so fast because everyone and their mother groups together for a Natalan party? Which, by my experience, is tanked by a 50WAR who practically can solo everything. As a WHM I was barely needed, unless BLM cast before Steel Cyclone, which ended in death in most cases by the amount of mobs they'd pull. I bet if you did leves the whole way from 1-50, it wouldn't be so fast.
