It's a great feature! However the values listed for the abilities are odd, at least for me -- they seem to all be based on a power of 48 (e.g. base attacks are all 68 damage, Deep Breath is 170, etc etc.). Are these values dynamic? Did I somehow select a power of 48, or is that the default? Or are these values static?
Having dynamic values based on power would be fantastic, but obviously I understand if that's not the case. However the nice thing about wowhead or 'competitor.com' is that the values are for a level 0 pet, ie they reflect the base damage and not the damage done by a pet of arbitrarily selected level/power. This allows you to calculate actual damage,
damage = (20 + power)(baseDamage/20)
