Where is my Mad King Outfit?
If you were wearing it before, just go talk to the Black Lion Armor Trader (next to the TP in any major city) and he will convert it for you. That easy 
Thanks Karizee, I found it.
They ruined the Mad King Outfit, when I change into it, I no longer have access to the special features unless I carry the extra staff, and only one character can carry it at a time, even so, it takes up more space. What was the design team thinking? If I would have known that they would do something like this, I never would have purchased it from them. This game keeps getting worse all the time.
