I don't really want to be that guy but a lot of the class descriptions are misleading and/or inaccurate... i.e. "Any DPS the Warrior will do will be outshined by every single other class in the game" is just wrong. The
Newbie wiki page has pretty good class descriptions. That said, if you're trying to give more "thematic" insight into class choices you're kind of on the right track I suppose.
(You also uh, forgot about wizards. )
