What kind of event would you expect during X-Mas?

Personally, I think this game has been quite generous in terms of free gifts, as seen by the events in mid-late August and many daily events.

I hope there will be some exciting skins (familiars and character appearance) for X-Mas, and I am looking forward to it. This is my first MMO, and, although I have mixed feelings about an entirely RNG based game, I have faith in it.

As a side note, has anyone noticed whether most skins on sale in lucky box have always been there or are they nascent in the bestiary skin collection?
