Why do people want updated models/animations?

So one of the things that keeps popping up in the expansion leak threads, and something everyone seems to want, is more updated models/animations. Why? I genuinely cannot understand why people would be so excited. Sure, its a nice thing to have, but we saw what happened in WoD. The updated model work took so much time and effort and left us with very little actual content. personally, i don't care how things look, especially since models are hidden behind armor sets, and animations are really not noticable during raids/dungeons anyway since usually its just a huge clusterfuck. Do people really want them to take time out of developing real content, features and gameplay in favor of graphics?

 

Please Help !
Thanks !

I didn't find the right solution from the internet.
