I also would love vanity weapons since day one. I also use a custom UI to make all shortcuts available pronto, but the feature to hide second-hand weapon is beautiful. I usually hide my shield so I can fight with just a sword in one hand, which is more my style than the two-handed, two-hands or S&S, although I also like them. Just with a sword is for me in more sintony with all of those swashbuckler films (which is itself a paradox) and Roy Thomas and gang’s stories of Conan. I grew up with one-hand sword fights, and still today am unable to find a game where I can be like that. That second-weapon custom hide is a godsend to my imagination. The two-hands barbarian looks awesome, cutting and punching at the same time.
But more in the thread:
I feel they would draw the line in vanity weapons. They would probably have to be from the same kind of weapon to make sense, specially because of the fatality animations (although waving a staff like two or one-handed would seem cool). Oh, look a new class idea.
It seems to me that both for armor and weapons it isn’t simple to do the change, or else they maybe would have already done it. I’m presuming here, of course, but vanity armor is an ability to wear a second armor as normal awhile disabling its stats and only the visuals of the first one. The class restrictions still apply. If that is the way it’s done, then changing – or even deleting – the restrictions would give a lot more work. It could give rise to some unforeseen bug (they’re always around). It may be a bit more complicated than simply saying “Ignore restrictions” to the code.
Since all the attention they can give to the game is for more urgent problems and maintenance… Well, we better not hold our breath.
Besides, many company games have some philosophy of how their games have to be for the players so they may have their own distinguishable characteristics (modus operandi, visuals, etc.) compared to others. Maybe it is the same policy here.
