Hello monks of Azeroth!
We've been so restricted when it comes to transmog this expac. Only being able to transmog fists to fists when i'm pretty sure you would like to equip those awesome swords on your back! I've worked hard for the WoD's challenge mode weapon because i really wanted to equip those insane one-hand swords, unfortunately i can't. They said something about combat animation related to our fists, blizz....just let us have more weapon choices on our back and we'll keep fighting with our fists!

Official forum, posts your opinions and we'll make dreams come true!

PS: hunters can transmog spears into two handed swords and staves
