Hi, so I don't know if anyone would actually be interested in these, and I mostly made them for my own amusement, but I've made a batch of icons using screenies from the MoP beta. I made several different characters and went through and made icons of many different emotes/facial expressions/actions for each model. I won't post any previews here, in case someone is really trying to avoid all spoilers, but if you are interested, the icons can be found
here.
Also, if anyone is not in the beta, but would like icons or screenshots of a hair/face combo or emote I don't have already, I'd be happy to take requests. Again, not really sure if people would even be interested, but I figured I'd post on the off-chance. =)
