Store Item - Murloc Costume

Hello,

I hope that his post is in the adequate forum topic.
So I've been making a suggestion about an item that's missing from the Store every week for several months now, and I just want to know if I am making the suggestion for nothing.
The item is called "Murloc Costume" - http://www.wowhead.com/item=33079/murloc-costume
This is available for purchase on Icecrown realm, and it's unavailable for Lordaeron.
Can anyone tell me what's the problem with just making the costume available for Lordaeron Store also?
I really don't understand why it's not appearing on the Lordaeron Store also, since it's just a RP item(Useless at the end of the day, but a must have for nerds like me)
Again, sorry if this thread is not in the right place(I tried to search the forum, and my best choice was to post it here in the Premium sub-forum)
