Yeah. I think that we should limit the classes descriptions to a few key categories:
Role (spellcaster, skill monkey, gish, etc.)
VERY broad overview of the flavor. Give closest PHB or official PrC approximation.
Give the most important details (e.g. the Theurge from Mythic Vistas: Medieval Player's Handbook uses more ritualistic details).
If racial or alignment restrictions exist, specify them.
So for example, I'm thinking a description could look like this.
Corwyl, Village of the Wood Elves (Green Ronin Publishing)
The Cerellian Knight
Low Tier 4 melee fighter, similar to ranger with the ability to boost his strength in a manner similar to a barbarian. Good only.
