I understand the Pandaren not needing an update

I understand the Pandaren not needing an update. I have sat there amazed at how many facial expressions my Panda face can do! Such as pouting, all serious, or happy! But Worgens need a update as bad as every other Race. They are low poly & their faces have no expressions like the Pandaren do. & that static "Perma Snarl" they have should only be visible when they are mad or growling. Hope Blizzard makes a high polyon Worgen using the Alpha Model that looks better than the current model.

Also, a "Use older Models" option needs to be added for those with Integrated Graphics cards, as these new models will cause wows requirements to go up.
