Some further thoughts from me as well, maybe those that do spend cash on SG scratch can throw better input to my thoughts/rambling.
Seeing SG items in base pso2 were pretty much time limited items you can't trade/ever get again. Having items come back in future scratches is a nice idea. Having them come back right again in the next scratch is way too soon and now gets rid of that possible appeal of time limited items. I think the better way to bring back SG items is maybe doing some kind of renewal/rewind scratches every so often, kind of like how we just had ones for AC scratch items.
