Everything about Worgen is cool, except Blizzard forgetting them 99,99% of the times. Amazing starting zone, probably the best I ever did, beatiful content and building, nice voice overs, sweet cinematics, running on all fours as "mount" and suddenly at level 20 everything disappears and they get stuffed in a tree in Darnassus and largely forgotten.
Yeah, sometimes it's hard not telling Blizzard "what the fuck did you just do?"
I spotted Genn in Stormheim, but I didn't spoil myself too much, it was a pleasant surprise.
