Would it be possible to have a second head slot exclusivly for purchased hats. The problem with the system atm is that we have to choose between looking cool/showing support for the game with purchased hats OR stat increases from in game hats. The increase in INT from fox hat ot STR from bear cape wins out over wearing an exclusive hat. I would personaly purchase more hats if you could keep bonuses from in game hats.
The way i imagine this working, is you equip the in game hat as you do now and recieve stat increase, but then you equip the purchased hat in a slot next to it, which is purley cosmetic, but changes the look of your character in the game world.
You would technicaly still have i.e. the fox hat on, but your character would appear to be wearing i.e. the witches hat.
