I didn't include neutral creatures because they have some incredibly powerful dragons that, when evaluated using my method, fall outside the acceptable range, resulting in completely biased information.
I suggest we have a discussion:
Regarding speed, I think it should be represented as a coefficient (I suggest 2% for each point of speed) applied to the overall score.
The "shot" and "unreturned strike" abilities: a coefficient of x2 to attack.
Double strike: something like a coefficient of (1.5-1.75), also applied to attack.
Flight: roughly 20% to the score.
Multi-target strike and biting multiple monsters: +15-30%.
Vampirism: (+ attack coefficient, converted into health and participating in the calculation of the defense coefficient) + (this coefficient, converted into attack and added to the initial attack coefficient) :)
Dragon strike (2 squares): +10-30%.
Remind me about the main abilities.
The rest: morale, magic resistance, double damage, mana drain and reduction, wall destruction :), etc. - somewhere around +5%.
In general, all these percentages should be calculated based on mathematical expectation (who is good at math here? :) ).
I'm waiting for your opinions! :)
