What animations would you change if you could?

Elezen bow, that final head tilt just seems so arrogant. Uhh...yeah also the running animations. Male elezen dance is horrid.

Both of these, so very much. The rest of the bow animation is fine, it's just that last backwards stretch like "there, I've been polite, now I can go back to being all superior."

(Double-annoyingly, it seems like NPCs already have an alternate "simple bow" that they use occasionally in cutscenes. A bit stiff, but a lot less overdramatic.)

The Miqote male sitting animation. Before switching to this race I had no idea how awkward their sitting pose was.

Use /cpose while sitting and there should be some alternate options - unless of course you've already done that and they're all bad. (I don't have a Miqo'te character.)
