I was part of the Warcraft 3 beta. When it started all the races felt so unique. It's a bit foggy now but I think, for example, all the elves buildings - which appeared tree like - would automatically regenerate. Once they started balancing the game, all these special traits fell away. All the races were homogenized and despite still being different, all played much more similarly. Honestly, it ruined the game for me. I feel if I had just picked it up upon release I would have enjoyed it, but watching all these unique traits and play styles fade away made me realize what could have been.
