OK, So I've been digging around the guts of the various dragons looking to create my own, and I noticed something when I checked what I made against Table 1–1: Monster Statistics by CR in the first Bestiary. Dragon average damage is over their CR by a lot. For example, an Adult Blue Dragon is CR 13 and averages 87 damage: 1 bite, 2 claws, and 2 wings (the breath weapon averages 54 damage), but CR 13 says it should average 60 damage. So the Adult Blue is putting out damage of a creature 3-4 CRs higher. I confirmed this with the other dragons, and it isn't just this one, they are all putting up really high numbers. I know that the table is just a suggestion, but that's a huge jump (+27 damage).
So are dragons supposed to be like this? If so, why, what's the purpose? Sure dragons are supposed to be powerful creatures, but shouldn't CR represent how powerful they are? If you need stronger creatures use stronger creatures, don't just up-jump the damage and keep the CR the same. That's just taking away rewards from the players. Am I missing something? Help me out here guys, Thanks in advance.
