Feedback request for PC dragon system

[Tyrann]

Hello everyone.

There is a dragon + rider campaign recruiting in the play by post section of these forums, and it's inspired me to at least start prepping for maybe running a similar game.
However, I've never really liked dragons being color coded for convenience and frankly the "normal" ways in which 3.5 handles dragon PCs is terrible.

So, I made a start with building a point-based system for PCs to use to build their custom dragon. It's meant to be able to take 2 levels of gestalt after, for an ECL of 12, and is meant to be played alongside level 12 gestalt riders.

The point based builder can be found here (google docs sheet)

So, what do you guys think? Did I miss any iconic archetypes? Is anything offensively overpowered? Or is anything too underpowered/expensive?
