want to add the number of each type of monster that appears in each zone, a rang if it can vary.
reasons:
1) to have a clear picture of how many of each species or profession you can expect to find in an area for farming purposes (such as farming collectables or tomes respectively)
2) can be relevant to coming up with a build, such as there only being 10 melee creatures in an area of 300 craetures total would negate the need for an anti melee build/hero.
cons:
some areas widely vary due to certain missions making this more complicated.
