If ESO would ever do something like a battle between Werewolves, Vampires and maybe hunters of those two creatures.
I think it could be a cool aspect to add in. maybe they will see this and go "not a bad idea" or maybe they already have it in the game and I just haven't witnessed it.
I think it would be cool if they did something where you could be a non vamp or non Werewolf and fight against them and you could get rewards to help you against said creature.
you could join 1 of 4 groups depending on your status in game Vampire hunters, Death dealers ( werewolf hunters, only used it because couldn't think of anything else besides werewolf hunters which would sound to generic) or you could be apart of the creatures Werewolves or vamps.
depending on if you won or lost the battleground you could buy gear that might enhance your skills fighting the respective creature.
Obviously if you haven't contracted the disease you'd be fighting one of the two and vice/versa.
I feel as if im rambling on. I work the night shift and its 530 am here so this might be a dumb idea. but I thought why the hell not. haha.
happy exploring. good luck!
