if your guild start mocking and bad mouthing you because you going to do some family event on december, then they are not a good guild. i told my guild and my friends that iam going to have some absent during december and everyone is either "no worries, me too" or "understandable, have a nice day"

The savage is not going anywhere, it will apply on december and it will be there forever, its not time limited event or something. if you want to do family event then go for it, that's a once a year event dont let the game dictate your life.
