Yea, I also say, that it might look pretty strange to see a hunter running around with a fist weapon.
But still, if I would see a warrior with cloth pieces in some "Tarzan-style", he would make my day haha.
It was just the idea of making your own style.
In my case it would be awesome to transmog the Cursed Vision of Sargeras as a shamy, or even warrior or pally :D
But still, for sure a warlock or mage would look pretty strange with for example warrior T6 , thats why I would be more up for transmogging only gear, you are able to wear normally.
...Poor cloth wearers ^^
