Avatar VS A:WOW tail flexibility

I don’t know if this has been discussed before and it’s just a lighthearted observation.

In Avatar, Neytiri and Tsu’tey are repeatedly shown to be able to raise their tails over the waists so the tip is at about mid back or head height. When Neytiri watches the atokirina land on Jake and when Tsu’tey makes his first appearance dismounting from his direhorse, this tail flexibility is clearly visible. I got curious and watched A:WOW just looking at the tails and I think that their flexibility was nerfed? I noticed that everyone’s tails consistently stayed below the waist, even for the Sullys who would have more flexible tails compared to the Metkayina. For example when Neytiri is mad at Jake at the beginning and is watching Neteyam be tended to, her tail flicks only at knee/thigh height. I thought this was an interesting change.

Has anyone else noticed this and was there an official remark about this?
