Dont you think that this it would be one epic looking weapon if it was available for transmog ? There are some epic weapons not allowed in game ! Like Umbra Crescent or tauren's Totem-like mace! Why blizz make them available for transmog? Just to make those NPC-s special and unique ? How would you feel wielding that weapon in your characters own hands ?
For those who dont know whats Umbra Crescent: It is an weapon wielded by Night Elf Watchers and by Maiev Shadowsong ! It is like big, round, two-handed fist weapon! http://www.wowpedia.org/File:Warden_artwork.jpg?c=1
But what sort of weapon it would be ? A two-handed sword? Naah. Maybe two-handed axe? More likely. I'd like to hear your suggestion about that weapon
It's a chakram, and chakrams actually have their own weapon type in the game files (which is obviously not available to players). Most likely if the chakram models were available to players they would follow the Warglaives' example and be treated as one-handed swords.
