[@Kho] I am a 1 Might dragon and I find this post offensive.

Anyhow, i thought it was established that the might expended in creating an intelligent race was set at 1. It says so in the OP and that's why I didn't really put more might in my dragons. 

And I always thought that ultimately, the key point to consider when dealing with a race's power level is the rate of their reproduction. Slower reproduction generally means a higher level of power per individual whilst higher rate of reproduction means having the advantage of numbers in expense of individual power.

This is my two cents, take it as you will.
