@DejaWukong You get the transmog even if you dont win the item, so thats a moot point. But since the set is also good for you its valid to roll, druids will be salty though because its "their" set.
Sure? But that's kind of an absurd comparison. Its an RPG, you dont get everything all at once, part of the power fantasy is getting stronger / richer as time goes on and the feeling of accomplishment that goes with it. You dont have to have dual spec immediately at 40, or you can make the choice to skip your mount for a few levels in favour of being more versatile.
