What? Why?
Who on earth working there took more than 5 seconds to look at this stuff in-game and thought "Oh yeah, this is a great look for party members to wear 24/7!"
Minor problem, sure, but it looks ridiculous and I'll stay away from any screenshots.
I think they had to settle for an expression that would make sense during combat and chose "angry".
Maybe the Xbox 360 didn't have enough memory to load in more facial animations. BioWare had a similar issue with Mass Effect 3 where you can't holster your gun in combat areas because the Xbox 360 didn't have enough memory to load all the animations.
