Diminishing returns for artifice

I think that it's incredibly boring that everyone's goal for a set of combat artifice is an identical set. This is simply because certain artifice, like snake skulls, are straight out better than the rest. Now, there's nothing wrong with encouraging people to get a skull or two, but having them in every single piece of clothing is kinda ridiculous, and leaves some of the lower end artifices completely useless (they can't compete for any slots with polished buttons etc). What I'm proposing is that the more of a type of artifice you have in your set, the less benefit you derive from them. For example, your first snake skull would give full benefit, but the second one would only give 75%, third 50% etc. Hopefully this would result in people wearing something other than the admiral outfit.
