This is a simple exploit that I found and decided to make an account to contribute and stop being a leeching fag.
So basically you would want to use this on Warsong for the Xmog Goggles.
This exploit basically allows you to use the Engi goggle xmog without actually have the profession anymore.
Guide:
Drop a profession for a minute like chanting or something.
Pick up Engineering and goggles.
Go xmog to it to your helm.
Drop engineering and get your other profession back.
I also tested trying to xmog the goggles without the profession and it doesnt work so this is an exploit.
I hope you guy can use this, I personally love the goggles xmog !
