The same thing caught my eye. The animations enforce narrow racial stereotypes.
I would like to play a Str based High Elf Fighter/EK in full plate, and when I saw that elegant dancer idle pose I thought it doesn't fit.
I might also play a human acrobat Rogue or Bard whom the "dancer" animations would fit.
D&D is trying to get rid of racial stereotypes too. The next edition is expected to not have fixed racial stat modifiers anymore. I wasn't convinced at first but now I think it's a good thing. Same goes for animations that assume certain stereotypes.
