I am much appaled by the over-emphasis of the prowess of the Occidental dragon. They were continually slain by humans, so what is the justification for the power increase? Nothing but the hubris of the inept designer. OTOH, if proper stats were desired, the Oriental dragons are the ones that need be vastly improved in their capacities.
This is not to say that I did not intend to beef up these critters in a revised edition of the AD&D game. I was planning to move the base HD from d8 to d10 or maybe d12, and give them additional attack damage equal to the number of HD possessed, this in an incrimental scale (intended) based on the HPs per HD possessed. As i mentined previously, all large and robust critters were to have gained d12 HD base, HP spread based on 50% of HD + a variable addition above that equal to up to another 50%, along with damage addition based on HD#. (I have dine this in the camopaign material I have created for the C&C RPG system.)
In short, I do not believe that dragons were ever or should be now, the toughest monsters in the marches, and I will not cave in to pressure to change my mind in that regard.
