Goblins take the prize.
Thing with worgens atm is their starting zone and their looks. They look amazing and the animations are cool.
But, today i had the opportunity to create a Goblin and got an instant laugh. It's still downloading the whole beta to my laptop, so i haven't been able to play with it more than 2 minutes, but from what i see, it's machines and crazy buildings allover the place, with people delivering quests in cars and all that sort of stuff.
Looking forward to take a look later and record a video :)
