Can't count the number of times i pass along a knight in a particular combination of 4 or 5* gear and think "0_0 ° ° (Dude, that guy looks awesome)", or just how much i am looking forward to see how my own particular gear will look once evolved.
Therefore, I'd like a model/doll you can dress up with any in-game available gear, just to see how it would look like, as well as help me to choose my costume items. Rigth now i'm on Skelly+Cobalt+Owlite and frankly, it looks a little too ecclectic to me. I don't know where you could put this feature, maybe, as you already have the "inspect" feature, something similar could be implemented.
I'd certainly enjoy my off-mist hours to try on some new clothes :p
