More than a year ago mannequins were told to be implemented after the 2.2.

A great 2.5 is now live, with a lot of stuff, and even more is coming with Golden Saucer casino. I greatly appreciate that.

But now my retainers are really, really, really full. And I had to sell a lot of pieces to the GC NPC, even some i liked. I was enjoying the idea of displaying all the best armors I managed to gather with all efforts.

Now, I think they put this idea in the bean, they don't event talk about it anymore... We also know the team responsible for these is working on the Casino, and other stuff... But please... Tell us if you still are on the work, and if yes, when will we be able to see them in the game ?

Thank you SE.
