Everything graphics had to be scaled down to be playable. Those animations are part of it. When I were in beta, had to quit testing because my PC were no good enough to play the game, and it wasn't cheap hardware.

To get them back I guess we need to wait several years, when graphics so powerful to handle something like the 1.0 will be in the average PC.

In the while, we can now enjoy a 2.0 Ul'dah full of life, rather than an empty town as we see in the linked video.
