The one I hate the most is the Elezen running/walking motion ... I love the look of elezen (minus their necks), but the run makes me switch from them every time I give it a go.
I also dislike mlae miqote running animations ... why do they do the shoulder lean on every step? Makes them look like they broke their back in 5 different places.
Au Ra male running animation is similar to the male miqote animation, they bounce as if they are on the moon trying to jump 10 feet in the air with every step.
The Au Ra's horns and helmets ... some helmets looks really good with them, other's .. well others just look like crap due to how the horns interact with the helmets.
The clipping of hair styles in certain armor/helmets.
Clipping of robes/skirts/ long shirts and the mounts.
