not everyone cares about lame cosmetics ya know. i only tried it for the apparently faster leveling which really dont seem fast compared to retail. i dont give a flying f about transmog. never have and never will. i also dont care for all this gem crap and sockets they added either and refuse to use any of it. i find it all useless personally.
is cool though that i can buy alot of ultra rare mounts from the vendor though 
they are only a +1 to the count for achievements btw. i will never look at em or ride em. i do like getting achievements
