Hello there, long time lurker, first time poster here.

It is clear that in the upcoming patch 1.20 the existing item system will be simplified into a two-pronged NQ-HQ system. However, it is still unclear how SE is going to go about the transitioning. Words surfaced around as if the NQs and +1s are going to be converted into NQs, while +2s and +3s moving into HQs.

Yet it seems SE has not addressed this issue openly. In the upcoming patch 1.19 we could attach materias onto items with a multitude of HQ properties. However, since there is still a possibility of +2s moving into NQ territory, it would be rather tragic to see +2 items gets converted into NQ items with multiple materias attached to.

If someone with reliable information could speak on this matter it would be much appreciated ~
