1.0 animations only looked good as long as you were running on a flat surface. Not suddenly going up a two foot steep climb because the devs realized how much a nuisance it was back then to have to run around even single little piece of ground that was more than a foot step high, because we couldn't simply jump over minor obstacles.

While they looked nice in general, I would never want them in dodge-heavy fights where I always want to know exactly where I'm standing without having to second guess the movement animation.
