In my extremely accurate and scientific polling (I read some twitter) I have discovered that one of Blizzard's biggest fears for the new character models seems to have been pretty accurate. Even though they've said (multiple times) that the faces on the new models are still a work in progress, I keep seeing the same reaction over and over again - "I really like the new models but my character's face has changed and now it's not as good/not my character." If you remember back to 2009, when the when are they going to update character models talk started being bandied about, you'll remember that being one of Blizzard's biggest arguments against doing it - people get very attached to their characters and think of them in a way that makes them very dangerous to tinker with.
So far it seems like people have a Not My Character's Face policy towards the revamp - they like how the new models are more detailed and are in general much more fluid and animated, but they still don't like it when the faces change.
So how about you? How attached to your character's face?
