So, disclaimer, this event would not be taking place on the actual holiday for obvious reasons.
But, if it were to be hosted as a neutral RP event, how many people would be interested in a sort of New Years Festival (Festival of Rebirth) being played out in January?
Something to also, you know, make up for the fact that the only Holidays Blizzard actually shows off are the ones you can easily host world events for and the most known and marketable holidays.
