I read some lore about orcs in this game and i want to make a suggestion.
Change the Marsh Orcs military bonus,you said they were massive in size(more hp or dmg or both maybe ) and have best mounted cavalry of orc,yet you gave them more hp and damage for goblins...goblins?!...come on,stay true to the lore/description.
"This is no rabble of mindless Orcs; these are Uruk-hai. Their armor is thick, and their shields broad."
