I might be somebody else, but I'll explain why social holiday stuff should be kept out: Barely half of the value of this kind of items is how they look: a very important part is the status symbol of it stating "I was there and I killed those pumpkins" or even better: "I was there 3 years ago".
A consensus solution would be adding replica's, which is quite a smart move they did this halloween.
One important thing you seem to need to learn about mmorpg's is: it's not about what you accomplish/how good you are; it's about what you accomplish/ how good you are compared to others.
And the reason why people are reacting heavily is that there is no way to tell what will be in and more importantly what will be in in some kind of future.
