do you have any information beyond subraces that would be provable post reveal? you arent exactly the first person to suggest sub races as a replacement of an expansion feature
anything new we havent seen ingame before? like new base animations to differentiate them, new voice overs, high elves or half elves with new models, upright orcs perhaps? elven undead.
atleast give some sort of details if you want to pull an i called it
