I don't know why so many people's arguments are "they are just for fun."
There is nothing fun about not being able to use holiday helms during actual gameplay.
Letting you use holiday helms during actual gameplay would make them be immensely more fun and there is no balance issue with it whatsoever because they would have the same stats as the already-available helms.
Letting the "holiday mask skin" be worn over top of your current helmet is an equally great idea and would solve the "low levels getting good helm too easy" issue completely.
Go ahead sign it's not going to make a difference at all. It's way too silly to see ppl running around with Dragon Mask and Pumpkin Crown with +1 modifiers.

They should have a hoilday armor that you can collect for fun...
