I have a hard time pegging what the class is intended to do? The class seems melee orientated but, lacks heavy armor or martial weapons.
Str and Cha would seem to be the primary stats of the class, but it does not have any Cha based skills w/o chosing the appropriate Dragon type, and then it is only Bluff.
Despite venerating Dragons, the class does not have spot or listen on its skill list, and thus can not be a good scout, even if one where to chose to venerate a Dragon type that grants Hide and Move Silently.
The Auras are cool, but seem an after thought, as you get them all by 9th level. Frankly I like the Monte Cook design philosophy for classes where there is a big list of possible abillities, more than you can ever take, and have to make choices.
I wish rather than making what Color Dragon to emulate trivial, WOTC had put in some effort and did something similiar to the Totem Warrior in Arcana Evolved and have your choice of Dragon signifigantly impact your class abillities. A follower of the crafty Green Dragon is going to be quite different than that of the Vain and powerful Red Dragon.
The game is called Dungeons and Dragons afterall, failure of effort and imagination on WOTC part.
Seems the best way to go is grab a level of Fighter for the Bonus Feat and Heavy Armor and Melee weapons and +1 BAB.
