Eh, I'm sorry folks, but when I read the description of this event, my reaction was "Bah, Humbug!" I will be surprised if even one player on the server gets any of the really good stuff (S grade stuff as I recall), much less several people getting the good stuff. Other than the event, GL to all.
I once meet a guy in Las Vegas who hit the jackpot just next to me...
I ask him how he did it, other than luck...
He told me that he pretty used about $5000 on the same machine and did not went to the bathroom for the whole time...
This event remind me of the same thing, in order to get the S/S80 weapon you must either have one of the follow two things: "one of a hell luck" or "500mil willing to be wasted in hope of increasing the luck you have"
If I was rich in this game, without a doubt in my mind, I will wasted 1bil buying the scrolls just to reach the highest probability to get the best, a good way to kill time.
But I am a gambler, thats how everytime I go to Las Vegas, get around $1200 just by playing Poker and Black Jack.
