I wish they'd simply have cont ent that is lite, not too heavy, as @Joel
states, 2 new quests a day not including repeatable from day 1 , event dungeons, and a small guild component. Cool. But how about something for the players who can invest time this Christmas?
I had mentioned before, make a difficult and long skin quest trial that rewards one of the holiday skins, make it out of 30 steps. Something , hardcores would love it , everyone who can do it, will.
But then people who can't do it , don't have time, would complain that it was too hard Grindy unrealistic ... or had to spend time family holidays travelling. Either way there would be complaints on exclusive skins or rewards offered behind difficult and time consuming stuff.
I personally want shade debut level of grind dedication quests (killing hundreds of light enemies), and Solaris flyer kills. I also want St Patrick's day tsume dungeon and valentine lady nimriel dungeon difficulties for event dungeons.
