This is my idea for how Blizzard should revamp the Creature type system. Nearly all creatures can have the following categories applied to them: The "Primary Creature Type" (or Base Creature Type), The "Secondary Creature Type" and "Tertiary Creature Type" (or Creature Size).
Primary Creature TypeEdit
A creature's primary creature types is considered its base creature type, for example a Plagued Swine's base creature type would be "Beast".
List of Primary Creature TypesEdit
Secondary Creature TypeEdit
A creature's secondary creature types is considered its second creature type, for example a Plagued Swine's secondary creature type would be "Undead". Not all creatures can have this category applied to them, for example a Defias Ambusher would have the categories Humanoid and Medium, but no secondary category.
List of Secondary Creature TypesEdit
-*While the Elemental category is listed under both the pirmary and secondary creature types, a creature will only be applied one of them.
Tertiary Creature TypeEdit
A creature's tertiary creature type is considered a creature's third creature type, for example a Plagued Swine's tertiary creature type would be "Small". This category usually describes the creature's size.
List of Tertiary Creature TypesEdit
Miscellaneous Creature TypeEdit
Some creatures can be found applied with a miscellaneous creature type. These functions a little different than most creature types. A creature using one of these categories, have no other creature type categoryies, for example a chicken is using the critter creature type, no other category has been applied to it.
