I don't think they're that much of a disappointment. (By the way, you used '4' twice in your list. GJ counting.)
#1 I don't think the models are poor. (Well, the Female one isn't GREAT, but it's not that bad anymore either.)
#2 I guess I'd have to agree there.
#3 I half-agree on this one. I don't think they're "horrid", but I don't think they're good either.
#4 I don't remember any offensive emotes for Male Worgen, and besides, lots of races have had offensive ones, they just usually don't last long.
#5 You were kidding, right? Have you seen Running Wild? I fucking love it, I'd easily trade 6 mounts for it.
