Since it was introduced for the first time, SG scratch in JP server has got an important update to have an "almighty ticket" for the given scratch. In JP, we can exchange 40 items from an SG scratch to get a special ticket, which can be changed to any desired item from the same scratch. The sacrifice of 40 items is a serious cost, still it is an "improvement" compared to the deep void we had to face when we couldn't get the desired item we truly wanted.
Now, in NA server, we get this "almighty ticket" as a bonus for playing the scratch 40 times. That means I get the almighty ticket,
while retaining all the 40 items I got.
Honestly speaking, I couldn't foresee this treatment at all, so I'm just sharing info.
