"We had been working on add-ons originally with the goal of implementing it half a year after the launch of A Realm Reborn; however, we were looking at features that would not create any inequalities between PC and PlayStation users and one of the reasons why we are behind on this is due to the lack of room to do certain things on the PlayStation, which was more than we had envisioned. Because of this, we have been prioritizing the implementation of other expanded features."
