Forcing every warrior into leather if they want to be able to deal with competitive damage also not an ideal "item design". It's also evident that Blizzard recognized that as they did a little to change that in the course of AQ as well as Naxx.

Transmogs are why I hate the idea of transmogs. If everyone is wearing a similar style statement it's dull. It's fun to race through Tauren Druids wearing full mooncloth. It's hilarious, however, it's also a smart idea.
