Vindictus Christmas Event - Waste of money?

As most players know, Christmas has arrived in the world of Vindcitus and is spreading holiday joy with spanking new costumes and events.... Or is it? Nexon has added the new Christmas Gift Box that costs 2000/box or 19000/10, and an event that gives rare Devil wings. The event calls for the fancy Christmas Cake that has a VERY, VERY, VERY slim chance of "popping" out. Even if one were to get the cake, all you'd receive would the devil wings that only sell for like.. 300- 500 mill! Where as one could have spend over $20 just getting them. In my opinion, the box is TOO over priced and not worth it. Although if they increased the chances of getting the cake or at least reduced the price to like... 1k - 1.5k nx per box, then it might be worth getting.
