I think that holiday items should be changed a bit. The normal holiday items should all be stepped up a bit per year. For ex a green festival talon from 2010 should be changed to elite festival talon and color should be changed from green to purple and from purple to pink and pink to gold which would be a new rarity.
This new rarity should not be droppable. It should be a veterans items. So all pink items from 2010 should be gold because theyre veterans items.
Also the vanitys from 2010 like the pumpkin hat and the reindeer antlers (quest items only) should be made golden and given stats instead of devs having to make new items for vet rewards.
Lastly the new gold vanitys should be tradable and they should not have cheap stats like founder helmet but rather a crit bonus or hit or h/m regen bonus.
