I did a little research on the vampire diaries novels and found the vampires and werewolves in the books way more capable, I felt the show had downplayed these two species greatly and made witches the uncontested top of the food chain. It kinda annoyed me when Klaus and Elijah would get stopped by no name witches so I decided to give the vamps and wolfs a boost.
