Tradable Holiday Items

Your logic is flawed. It doesn't matter if there are a large amount of masks if they are all being held by a small number of players. If the server ever gets considerably more popular, anyone who has masks will become absurdly rich for reasons that they barely put any effort into. The economy would begin to focus around holiday items, and players would buy less resources and goods in favor of saving up for holiday items. Therefore, it would significantly damage the economy.

The only thing that having a large number of masks would do is lower their price in the short run. Thus, I voted no. If they were untradable though, they would be fine.
