Jin Compensation was created a while ago, I believe even before the Upgrades came along and during the PH Migration happened.
And it was mostly to provide a boost in their currently weaker items compared to what Ran users had and compared to what PH players obtained once they merged their characters. There was no revenue generating perspective when we held this event and it was primarily to assist those users limiting it to no Philippine users being eligible for this compensation provided. Any equipment obtained through the Item Mall was also not eligible to be "boosted" it was only for items they possessed prior to the PH and Ran Merge.
