The older racials?
I never really understood why they felt it necessary to change them into what they are today...I thought they were roughly equal in power and popularity. They were powerful racials, perhaps, but then again -- the humans and blood elves were the most popular races, so it was still fairly balanced between them.
Do you want them to be the racials they once were? Because as they are now...they are not particularly useful, in my personal opinion.
