Still unclear. It only specifies that it determines the service plan during the quest. How does that relate to the reward items that you paid for in the cash shop? There are pictures of items, and a price tag, and buying the cash shop item still does not equal getting the items.

Instead of:
* In the event both you and your partner have different promise wristlets equipped, the wristlet of lesser value (standard < gold < platinum) will determine the service plan for both players when undertaking the quest "The Ties that Bind."
It needs to say something like:
* In the event both you and your partner have different promise wristlets equipped when you undertake the quest "The Ties that Bind," the wristlet of lesser value (standard < gold < platinum) will determine the service plan and quest reward items for both players.
Or, more bluntly:
* In the event both you and your partner have different promise wristlets equipped when you undertake the quest "The Ties that Bind," the wristlet of lesser value (standard < gold < platinum) will determine the service plan and quest reward items (mount, attire, etc) for both players. Undertaking the quest will also destroy your promise wristlets and you will not be able to recover them without paying the fee again.
Or, completely transparently:
* In the event both you and your partner have different promise wristlets equipped when you undertake the quest "The Ties that Bind," we will steal your money and give you no restitution or recompense. Consider yourself warned.
